Cancel multiple Purchase orders in mass

Hello,

We have multiple Purchase orders that are currently still open, there are no invoices matched to these purchase orders, and we need to cancel them. The initial thought was that we could use an interface file to update the quantity for these purchase orders to Zero; this would follow the process that we have in place to cancel purchase orders but given the number that we have to cancel we seem to be running into some performance issues with processing the interface files through OIC (even at 132 lines it is taking some time to process).

Is there a method in ERP where we could cancel purchase orders in mass? Canceling via interface file is taking longer than expected and manually canceling the purchase orders is not going to be an option. Is there a faster method available?
