Tax line to split based on revenue Distribution in Multifund accounting

We are usingMultifund Receivables Accounting Journal entry rule sets and we are definingreceivables code combination and tax Code combination from auto accountingsetup and revenue we are putting manually after completing the AR transaction.

 

We are splitting based on primary balancing segment ,  while putting the revenue lines indistrubution we put two different code combinations ( only Primary balancingsegment is differnt) and we want accounting to split in these two reportingentities.

 

However , from multifund we are only getting a split in receivables but not tax. we also wanttax line to also split automatically into two different Primary Balancingsegments ( not in same primary Balancing segment) . While entering codecombination in distribution we dont want user to put tax combination.
