LR Print Layout Request -- A New Start

Question

After some discussion on another thread, here is a new start, trying to detail my request to improve the layout functions in the Lightroom Print Module. These requests are for common layout requirements for those of us who do other printing than single page Fine Arts prints. The current layout functions in LR are essentially limited to Fine Arts and Contact Print functions. The requests below are for the rest of us.
Please note that these requests are only about LR Print Module LAYOUT functions. Requests about soft proofing, output sharpening, etc. should be handled in another thread.
Request that print layout functions include the ability to:
1. Precisely place multiple cells of different size and orientation on a page.
2. Automatically place as many images as possible of a given size on a page, making the image orientation as necessary. For example, three 4 x 6 prints on a single 8.5" x 11" page. Wedding shots, for example.
3. Allow creation and saving a job of multiple pages with the ability to have different page layouts on each page. For example, a twelve page monthly calendar where some pages may have a single landscape image with no caption. Some may have a single landscape image with caption. Some pages may have two portrait images with or without captions, and some pages may have all of the above.
Consider that on a landscape page, there could be two portrait prints with a single landscape caption below and spanning both portrait images.
Another example to show the need for this is when making a Photo Book. Most often, each page will have different layout requirements.
It should be possible to save and recall both the entire job with images and just the layout alone. Maybe a Print Job Collection and a "Print Layout Collection."
With the implementation of 1. above, a separate caption option isnt necessary since it can be created as desired as a separate cell with text created in Photoshop or some other application.
4. Be able to create a template for a page(s) and place selected images in selected cells. For example create a template for a greeting or note card that will be folded after printing. The portrait page template could have two cells. The outside page could have an image in the bottom cell only, and the inside page could have images in both cells, or any combination of the above. The point being that an empty cell should be possible.
5. Be able to replace or remove any image from any cell on any page when desired. That is, be able to add, remove, or replace an image in a particular cell without changing the remaining layout.
6. Be able to insert or remove an image from a page and have the entire layout change accordingly. For example, I just found the perfect sunset to insert after the thunder storm. This is the inverse of 5.
7. Provide trim marks for page cuts when a final page is smaller than physical page. This situation has just come up in Christmas cards that will be 7-7/8" x 10-1/2", printed on 8.5" x 11" paper. By the way, I dont know of any other application that can do this.
These are all some detailed request to implement the general request to be able to place any image in any orientation anywhere on a page.

Answer 1

And I would add that the form of this regquest is just about perfect...about the only thing missing is the "why would you want to do that" part with potential examples of how you would use certain aspects of the request to do certain commonly needed tasks.
For example on #2, are you asking for the ability to maizimize the number of images up on a sheet to make prints more efficiently? Would you also want margins and trim lines? (personally, I would as an option).
#3 has a good example for the suggestion/request. But another example of use would be to be able to print off custom brochures either for the photographer (self promotion) or as a service to the client.
You say you want the ability to swap images in an array (I do too). Would you want to do this by drag & drop (say yes please)?
This is much better...
