Fulfillment workflow for SO's with both inventory & drop ship items

Hi There,

I can't figure out what NetSuite intended the workflow to be for the following scenario, and I could do with some help!

We inventory some items, and drop-ship others.  A single order often contains items in both categories.  Approving the order causes a PO to be generated and emailed for the drop-ship items.  Then when we get shipping confirmation and tracking numbers back from the drop-shipper we use the "Mark Orders Shipped" page to enter tracking number and mark those fulfillments as shipped.

Meanwhile, our warehouse wants to ship the items that are in our inventory, so they go to the "Fulfill Sales Orders" page.  But this shows all sales orders with any items that haven't been shipped, including those where all the items are drop-ship items for which a PO has been created (and are therefore of no interest to our warehouse).  So the warehouse person has to open every single sales order in the list, and manually check to see if there are any items for him to fulfill.  This has to be done every time orders are filled from the
