Old Goods Receipt Notes on Accruals listing

Hi,

Is there a way of purging old GRNs from an Accruals listing without going to the trouble of doing a Return to vendor transaction.  I have a number of Receipts 12+ months old on the system. Suppliers have been contacted and have confirmed no liability, nor is there any invoice on their statement. Is there a way of ZERO matching eg put up a zero value invoice to match agains the GRN and thus remove from the Accruals listing
