Crystal PO Form Warehouse Availability

I would like to have the warehouse to which parts are being purchased show
up on the PO, if the parts are being purchased to stock. The Warehouse
Code field is in the PORel table, but is not available to the Crystal PO
form in Version 3.0. Is it available to the Crystal PO form in 4.0 or 5.0?
Thanks,
