Purchase Order re-confirm Ax 2012

We have a PO with Purch lines.First of all we do the Confirmation by clicking on Confirm.

After that we change Overdelivery/Underdelivery for a purch line and we need to reconfirm the PO.

Question: Exist a solution in standard AX to maintain the confirmation and not to reconfirm every time we change Over/under delivery.

Please help,
