Journal Entries Using Foreign Currency Rates from Blanket Agreement

GL entries created when consigned material is 'consumed' or transferred to regular is based on foreign currency rate captured at the time consigned blanket agreement was created. Standard Oracle functionality defaults the invoice match option to PO when creating a consumption advice, so there is no opportunity to use receipt level matching to align the receipt transaction date with the current currency rate. 

Would like to come up with a solution that automatically generates GL entries created from consumption transactions that are more in line as those generated when invoice match option is set to Receipt, so that the currency exchange rates are current with the receipt transaction date.
