BPM to Set PORel Plant & Warehouse to POHeader Plant

How do I set the Plant and Warehouse on a newly created PO Release to be the same site as the Ship To on the PO Header, as well as the default warehouse for that site?

The system defaults to setting it to the current site signed into, rather than the site chosen on the PO Header when a new PO Release is created (whether through creation of a new line or a new release on an existing line).
