Process to create a PO and deliver material directly to subcontractor (v12)

SOLVED

In v12 - I would like to create a purchase order for a raw material but have the material delivered directly to my subcontractor.  My question is how do I configure this correctly?  The vendor of the raw material is unrelated to my subcontractor. 

My thoughts: I can "create" a second address for my purchase site (that is actually the subcontractor address).  I can also set the "receipt" location as my "subcontractor location" but both seem incorrect - and room for operator error.  I am trying to use the normal PO menu GESPOH; with almost all fields available in the entry transaction.  I will create a subcontract order (later) for the finished good they are making and their service (under subcontracting orders - GESSCO).
