How to derive bill to address in PO as same as ship to address from requisition - Oracle fusion P2P

At present we have updated the supplier site assignments window to derive the ship to and bill to addresses as same in the purchase order.

But we have a business requirement for a specific country, BILL TO address in the purchase order should be derived from Requisition SHIP TO address.

Please suggest how to derive this.

Thanks and Regards
