How to bill a supplier/third party in third party repair process (Cross Dock Repairs)?

Scenarios:
Company XYZ sells a product "ITEM1" to customer ABC.

"ITEM1" is a supplier manufactured item for XYZ.

In case of of repair, when customer ABC sends the item to XYZ, XYZ sends the entire unit Supplier. This works perfect according to the third party vendor process flow.

My query is, if this unit is out of warranty with respect to supplier, how will we pay the supplier? One way is to manually create a purchase req and PO. Is there a better way of doing it, which is directly initiated from Depot Repair module?
