Trying to make a BOM that takes multiple inputs and produces multiple outputs.

Hello. Currently we do the following for routing our parts.

Assm1
......Part1

........BOM: Steel Sheet 48 x 96 x 1/8", 0.20 sheet each

.....Part2

........BOM: Steel Sheet 48 x 120 x 1/8", 0.04 sheet each

.....Part3

........BOM: Steel Sheet 60 x 120 x 1/8", 0.8 sheet each

We have an order to make 25 pcs of Assm1 which takes 1 each of Part1, Part2, and Part3.

They have asked me to figure out if there's a way to make a BOM for running 25 pcs each of parts 1, 2, and 3, and input the sheets we know we will use based on our nesting program.

So it would look like

Output: Part1 x 25, Part2 x 25, Part3 x 25
