Create Purchase Order directly from the Planned Order (Planning) without the Purchase Requisition

We understand that system will create the Purchase Requisition automatically from the Planned Order followed by the Purchase Order. As per our business requirement, we have to skip the Purchase Requisition (i.e.) the Purchase Order has to be created automatically from the Planned Order (Planning) without creating the Purchasing Requisition. Is this functionality available by any chance? If yes, kindly request you to share the steps for this activity.
