Non-Stock Items in Produmex

Is there any capacity for Produmex to deal with non-stock items during the picking and dispatch flow? 

For example, we have some very low value  items that are set up as non-stock, and are basically printed on demand for specific customers to be included with orders.

We want a way to ensure these items are "delivered" as part of the Dispatch process somehow without having to create additional manual deliveries in SAP.  They would not necessarily need to show up as part of the handheld piking process but we would like to deliver them. We could configure them in a Produmex or Non Produmex warehouse... doesn't really matter which. 

Any thoughts / links / pointers much appreciated.
