V2 made this easy - there was a pane at the bottom and I added the labels to the batch in the order in which I wanted them to print and them printed the batch from the same screen.
V3 has no similar functionality and the labels print in seemingly random order from the batch.
This isn't good because we need the labels to print out in the order we add them. This way we're not switching back and forth between packaging types while packing the orders. It speeds things up and cuts down on packaging errors.
