Update Distribution Account when PO matched

Hello;

The Receipt Accounting Accrue Expense Items was incorrectly updated from Period-End to Accrue at Receipt.  This has resulted in the invoice distribution line, displaying the default Expense AP Accrual Account instead of the distribution account when invoice are matched to PO created within that period.  Without having to recreate the PO, is there anyway to have the distribution account reflected instead of the accrual account?
