Debit memo created automatically through RTS needs to be placed on hold automatically

Summary:

Business needs to be able to place Debit Memo created from RTS on PO on hold automatically as they will need to block it from getting selected for Payment. Also they are getting Credit memo from supplier for the returns which have a different number. So they also wants the hold to block accounting for the invoice so they can change the Debit Memo number manually as per what is received from Supplier.

We have already verified the system options and other avenues and couldn't get any functionality to be able to meet this requirement. Please advise further?
