Can you base change order approval rules on the change order buyer?

Summary:

Content (please ensure you mask any confidential information):

Occasionally, the buyer on a purchase order and the buyer on a change order differ. For example, Person A submit a purchase order. Person B, the change order initiator, assigns Person C as the buyer on the change order. We are only seeing an approval attribute for Change Order Initiator, but would like to base it on change order buyer. Does anyone know if this is possible?
