I've added the ability to save any amount of units as a template, which will show up for you while building a list as though it's another unit.
At any point in your list building process, you can name and save your list as a template. For example, save Luke Skywalker with Force Push, Jedi Mind Trick, and Emergency Stims as "Decked out Luke", and that will show up alongside Luke as an option to add to future lists. Or, of course, Rebel Troopers with Z6 on them, and save yourself a few clicks.
Hope you enjoy!
