Can an Open PO price be updated based on new entries into Supplier Item Price?

Our company does not used "jde" blanket purchase orders.  A purchase order detail line may have been entered two years ago with a large quantity and the price at the time of entry.  We issue receipts against the open PO Line, so our Open Quantity is remaining to be "re-priced".  We have updated the Supplier Item Price catalog with new effective pricing and desire a batch program that will pickup the new Supplier Item Price for the Open Quantity.

On Enterprise application 9.1.  Any assistance will be appreciated.
