Notification sent to selected offer approvers only

Summary:

We have a long lists of offer approvers as required in some roles. approvers normally get email notification if offer needs approval or offer is accepted. Is there a way to among these offer approvers to only select who needs to receive the notification? I can see that the only way to assign notification is by selecting the Offer approvers (as in whoever is assigned as an offer approver) but just want to check if there is any other way to select. Thanks
