adding another recipient to a returned requisition notificiation

Summary:

How can we add another recipient to a notification that a requisition has been returned by the buyer?

Content (required):

Currently, when a requisition is returned by a buyer, the preparer/requester receives a notification that the requisition has been returned. We would like all approvers in that requisition's approval workflow to receive a notification when a requisition has been returned by the buyer. I've searched all Oracle resources and Google and I'm unable to determine how to make that change.
