Create shipping documents for drop ship

We want to use the drop ship process to generate a PO linked to a sales order line.  Everything works as expected, the sales order creates a requisition then the requisition is converted to a PO.  When we receive the PO into a virtual location the ship confirm immediately occurs pulling the inventory out and closes the Sales Order line.  The question is can we automatically generate the shipping documents during this step?  We want the supplier to use our shipping documents to send with the order.
