BAPI/Pointers on merging multiple sales orders

Question

Hello Gurus,
I have a requirement to create a sales order with reference to multiple orders. I have used BAPI_SALESDOCUMENT_COPY to create the first order with reference to the original order, saved this order and then modify this order with the data from the remaining orders (by reading the data from the order using BAPI_SALESORDER_GETDETAILBOS). This is turning out to be very complicated as we are using BOM and I have to change the item number and the higher line item number of subsequent order data that I am including in the merged order.
Is there a better way of doing this? Is there a BAPI/Function Module available to create a sales order with reference to multiple orders?
Any help or pointers to achieve this requirement will be helpful to me.
Thanks in advance.
Thanks,
Sandeep

Thanks Rob. We have the copy controls set so we will need the data to be transferred from the original document to the copied document.
In Createfromdat1 or createfromdat2, where do I specify multiple referenced orders?
As an example if I have the following orders in my system:
Order 1000                            line 10
          Line 20
          Line 30
Order 2000                          Line 10
          Line 20
Now I need an order which has the line items from both these orders:
Order expected:                 Line 10
          Line 20
          Line 30
                                          Line 40 which is  Line 10 of order 2000
          Line 50 which is  Line 20 of order 2000
