Suggestion: Have the ability to just have a list of sets you use, and with the press of a button, add them to your team.
Sometimes I like using the same Pokemon and set multiple times, and as I delete teams to declutter my roster, it gets difficult to keep track of mons that I like to use, even if I write it down somewhere, which, unfortunately, is often lost. Or sometimes I have a set I want to use, but the team I am currently building is not the right place for it, and I want to save it in a convenient storage space for later, where I can quickly add it to a new team, and I feel as though a convenience like this could really help.
