How do I update default Receipt Account rules to allow Req account to populate in Receipt accounting

Our current Receipt account mapping for Expense uses the Company and Cost Center from the Deliver-to location and the Natural Account mapping to Categories. This mapping is also the default for Requisition accounts in RSSP.

We have a need to override this mapping to use an account selected as the override to the default as updated on the Submitted Requisition. Job review shows the Requisition and Transfer Order both include the override account. The Receipt Cost Distribution process is setting the Charge account back to the default based on the Deliver-to Company and Cost Center and the Item Category Natural Account mapping.
