Ship To for PO created from EAM Requisition

Would anyone know of a way I can get the ship to default from the EAM location from a PO created from an EAM requisition? My customer wants the field to be automatically populated and from what I am reading in the documentation the Ship to defaults from Purchasing setups, the supplier or supplier site. The default in my case is corporate and this is not acceptable - they want the location of the facility manager. Generally this would be the same as the location address.

Thank you to anyone who can provide some guidance.
