BOM Template - add a column for Top Level P/n??

Like the title says.. Is there a way to make a new BOM template that places the "parent" Part number (ie the part number of the assembly itself) in every row on the BOM table? We need this to export out for another program and was hoping to have SW generate the BOM in this way.

For example:

Bom for 1234567
Parent P/NPart NumberQuantity
123456711123414
12345676542315
1234567878716
1234567151517
