I got an idea! Lets say you have 26 pages, with 4-6 slots on each page. Designate each page a letter, And then alphabatize each page. Like, the A page, would have AA first, then AB second, for example. The slots on 26 pages would be best, or you can get one with like 60 and mark 2 pages as a letter
But do you see where I’m coming from?
