Restriction of GRN Amendment for POs with Paid Invoice

Business would like to explore the functionality of restricting correcting/returning PO receipt when there is a matched PAID invoice to the PO. For now, we have managed to test the 25A opt-in feature 'Prevent Receipt Corrections or Returns Below the Invoiced Amount' where system is able to restrict GRN amendment when there is matched invoice (even if invoice is only in draft). However, this does not fully solve business' issue as they would like to have this functionality only applicable for PAID invoices. Can know if there is an existing functionality / workaround that can be done with this?
