COPA - SD - Rebates accrual & Credit memo

We have rebates accrual posting from SD-

Dr. Rebate A/c (PL) 1000 - this would also been in COPA

Cr. Rebate accrual (BS) 1000

Now you settle the rebate(credit memo) - say you decide to settle for 1200

At this point the system will do the following entry (in FI):

Dr. Rebate accrual (BS) 1000 - posted to COPA

Cr. Rebate A/c (PL) 1000

Dr. Rebate A/c (PL) 1200 - Posted to COPA

Cr. Customer A/c 1200

hence the difference of 200 will be posted to COPA.

The issue is that I want to separate reverse of accrual and actual rebate in COPA i.e. to have two COPA line items

first (accruals) -1000

second(rebate) 1200

instead of current 200

Is it possible?

Thank you in advance.
