Linked POs - Outside Service

We purchase material and it is not received here.

It is shipped directly to another vendor to perform service on the material.

After that service, it is physically received here.

How can this process be improved from what is described below to limit the number of transactions required and allow better visibility to the material.

1. PO to purchase the material.  In notes on this PO, specify where this is to be shipped.  (Outside service vendor)
2. When Vendor 1 ships to vendor 2, receive the material into Acumatica. (ask vendor to notify us when this occurs)
3. Create a production order with the outside service (nonstock item and material)
4. Create PO from the production order for the outside service.
5. Send it out for service in Acumatica
6. Receive it into stock on the production order

Thanks!
