Re-Assigning Buyer To An Approved Purchase Order

Question: E-Business Suite 11.5.10CU2 Procurement

We have received a requirement to allow our purchasing managers the ability to re-assign approved purchase orders from one buyer to another.  Currently I have found that from the Pruchase Order screen, while logged in using Purchasing Super User responsibility, that I can only take owenership of the purchase order myself....I can not assign it to another buyer....does anyone know if there is a way to accomplish this?  I know you can do this for requisitions via manage buyer workload, but I have not found a way to do it for purchase orders.
