Controlling Debit Memo creation date

Hi,

I understand that if we check "Create Debit Memo from RTS transactions" at the supplier level, the debit memo gets auto generated in Payables. I want to know, if there is a way of controlling the creation/generation date for debit memo.

If I have an supplier invoice for $1000 with creation date 1st Sep and I did a return of goods after few days, the debit memo gets generated with a date after 1st Sep. Now, If I do payment through payment manager with a due date of 1st Oct, the debit memo does not gets selected. I want the debit memo to be generated with 1st Sep date (Invoice date), so that both the debit memo and invoice gets selected and I can make the final payment. Is there any way, I can achieve this.
