Non-conformance against a subcontract operation cost determination

I need to create a non-conformance against an outside operation subcontract (OV) and want the DMR cost to be the PO price, not the cost of the part as of that operation. Can I force the “cost” dollars of a NCR/DMR? We do not want to create the NCR from the PO through Inspection Processing; we want to pass the inspection processing to the job and create the NCR from the OV Operation, but with the PO costs.
