EBS R12 Purchasing: Is there a way to have copied PO's pull item data from the Item Master?

When users use the copy document function in purchasing, the function populates item attributes from the copied PO and not from the Item Master. This causes a problem for Hazmat Items. If the UN Number and/or Hazard Class on the item master have been updated since the last PO, the client can be subject to violations and fines for mislabeling hazardous material. Does Oracle have functionality that would allow a client to set a configuration or profile that determines from where the copied PO gets its item data.
