Is there a way to change payment terms on AR transactions that came in via Autoinvoice Interface? (O

These were converted sales orders and the wrong payment term was assigned on the order. Some shipped lines interfaced to AR resulting in invoices with the wrong payment terms, schedules, and due dates.  We tested crediting the invoice transactions and then re-billing via copy transaction, but the payment terms are not update-able and do not default from the customer record (correct terms are assigned to the customer record). Is there a better way than asing the Receivables clerks to manually generate each invoice?
