Auto dispatched non-stocked inventory when order is finished packing in WMS

When a user applies a fully dispatched date to a sales order Cin7 helpfully fully dispatches all the order lines.  However when a order is fully picked and packed in WMS Cin7 sets sets the stage to dispatched (as per the settings configuration), but the non-stocked product lines are not marked as dispatched.  Would it be possible to automatically dispatch these non-stocked products lines so that the process matches the Cin7 one?
