Recursive Region table: is it possible to show the name of the assembly of the component?

Creo 4 M070

Is it possible to get the name of the assembly of the component inside the recursive bom region table in a drawing?

I ask this for an idea to manage recursive tables: if the assembly name contains the main assembly name, show it in the table, if not, filter it out. This way, if I add an subassembly containing the name of the main assembly, this will be shown as recursive, else as flat. I know that this can be done manually, but I want to prevent human errors.

For example:

Assembly "Assy1.asm" contains "Assy1_1.asm" and "Assy2.asm"

Assembly "Assy1_1.asm" contains "Part1.prt" and "Part2.prt"

Assembly "Assy2.asm" contains "Part3.prt" and "Part4.prt"

=> in the table : Part1.prt, Part2.prt and Assy2.asm
