So it’s not super beautiful, but if you allow your intermediate pieces to “sell” for 0 then you can generate a shipment, and once work comes back you only must “Re-Open” that previous shipment for the work and cancel it, it returns the stock back into your original warehouse.
It’s fewer steps than moving the stock into a different warehouse representing dropping it off at the client using the advanced stock transfer functionality, and it is much easier to associate with the overarching project and keep tabs on which order specifically this stock belongs to, but it’s not … nice … at all.
Probably I will go into the advanced stock transfer way.
