R42800 GL distribution

I'm working on invoicing a new product line we are bringing into JDE. The invoicing GL distribution requirements seem to be outside of the scope of the R42800. I come here looking for some opinions ideas

Example of something I can't find out to do.

GL Cat Code 1001: pull from transportation the billable freight for the order. (Freight is included in the price so it's not line item) - that much goes into a freight rev account

GL Cat Code 1002: List Price minus 10% + an addition NI line added manually - that much goes to another account

Remaining Balance goes to another account
