Ideas for Adding a "One Click" Print Button to VA01 Overview Screen

Question

I am not an ABAP developer and am doing some preliminary functional investigation to determine the best way to add a simple "one-click" button that allows a Sales Order Confirmation output to be sent to the printer.
Can someone that really knows, tell me whether or not a custom menu item can be added to VA01 and VA02?
I have seen lots of threads telling folks how to find user exits and menu exits for a program so I don't need that advice.  Rather, looking for someone who has already investigated this for VA01 and VA02 and knows the answer.
Problem Statement:
Our users would like a "quick print" button on the VA01/VA02 application toolbar that immediately spools the Order Confirmation output to the printer. Our users want to print the output on demand, i.e., they do not want the output to automatically be printed when the order is created because a printout is not always needed. We already have condition records created with Dispatch Time set to 3 - Send with application own transaction. However, it takes 7 or more clicks to print the output on demand by navigating the menu (Extras > Output > Edit...Further Data...etc.) and changing the Dispatch Time to 4 - Send immediately when saving. This is a big ergonomic issue and a time killer.
Although the number of clicks to print are less when printing the output from the VA02 initial screen (via menu Sales document > Issue Output To), this is not acceptable when creating new orders. Really need an on-demand, "one click" quick print button on the VA01 screen. As an aside, we have a totally custom transaction for preparing sales order data (shopping cart-like way of finding materials and entering required data) that then calls VA01 and fills in all of the information. When saving in VA01, the user is returned to our Z-transaction so asking the user to subsequently run VA02 to print is not practical.
Current Output Determination:
We have custom output type ZBS0 (copy of BS0). Condition records for print medium are set to Dispatch Time = 3.
Ideal Solution:
Add a Print Icon to the application toolbar as described above.  From the button, write custom code that calls RSNAST00 (or is there a better way?) to send the output to the printer.
Any feedback on how others have solved this problem would be greatly appreciated.

Still looking for input from anyone that has had experience trying to add a menu item or toolbar button to VA01.  In our case, for sending output.
Madhu,
Please again read my Problem Statement in my original posting for the business requirement.  We are using ECC 6.0.  Yes, I know that transaction VA02 has Sales Document > "Issue Output To" that allows you to print.  However, we want to be able to print from the VA01 Overview screen after all of the sales order information has been entered.  We would like to be able to click a print button which would save the new sales order and immediately issue the output.  Again, we do not want the output to automatically print for every new sales order - we want to be able to print only when needed.  The conditions that a sales person would use to decide to print a copy are too numerous or varied so they cannot be automated in a condition record.  Of course we do use condition records for creating the output but we do not send immediately on save.
When creating a sales order, the sales person does not want to do the extra clicks and key strokes to then navigate or open a new VA02 session to print from the VA02 initial screen.  And as described in my original posting, it is a lot of clicks navigate the VA01 Extras > Output menu to change the output to print on save.
If you observe the "day in the life" of a sales person and see all of the key strokes and clicking required to create an ECC 6.0 sales order, you understand why the extra 7 to 11 clicks to just print an output is very annoying.  We have created a totally custom Z-transaction that allows our sales folks to capture everything need for a new sales order all on one screen with no tab views.  We then launch VA01 to fill in all of the data entered in our custom transaction.  This all works very well and is a huge time saver for our sales staff.  Now we are looking to save a few more clicks by simplifying the printing.
