How to Send Purchase Order Notification to Both Supplier and Buyer Without Using 'Communication Meth

Good afternoon,

is there a way in Oracle Procurement to ensure that the email notification sent to the supplier upon purchase order creation is also sent to the buyer? I am specifically looking for a viable approach within the BPM Workflow tasks to achieve this behavior. Alternatively, I would appreciate any recommendations on how to route the notification to both parties without relying on the 'Communication Method' field within the purchase order setup.
