Manual grouping

It would be good to be able to check the box next to the orders and group them manually for batch label printing. I have dozens of items that are the same size and weight, only the design is different, so they could all be grouped, but I have to create a label for each one separately. Can you add this? They have this option in Etsy shipping so I know it’s possible. It would make it so much quicker to ship. Thank you!
