Hello Andy,

Thank you very much for your request! We actually have a current feature with our Packing Slip Editor that seems like it would be a good fit for your request. 

You can select how to sort the shipment line items by editting the "{{ shipment.line_items | sort: 'name' | columns: 'sku qty name price location' }}" variable. For example, if I'd like to sort by location, I would change this variable to: {{ shipment.line_items | sort: 'location' | columns: 'sku qty name price total' }}. You can learn more about these options here.

Please let me know if you have any additional questions or if this feature meets your needs!
