Auto print packing slips only for taged customers

[heathert73]

I would like to have a feature that would automatically print a packing slip/list when the label is printed for ONLY orders that are tagged or otherwise identified as requiring a packing slip with their shipment. Furthermore, printing the packing slip/list template assigned to the recipient company would be important since some of our customers have different needs when it comes to their packing slips. 

We do not include packing slips/lists in most of our shipments.  The customer receives their packing slip via the email that is sent from SS.  However, we do have a handful of customers that do require a packing slip to be include with their shipments.  I currently have tags assigned to these customer and I am using the alerts to remind users to print and include the packing slip.  An automated function would reduce user error in this capacity. 

Thank you
