Please cut paste Item Sets in the new client

I read I'm in the minority that use it but I have a bad memory and only started playing this game with bots when s6 started, so I honestly can't remember all the items for every champ I own, especially with all the changes going on every patch and me looking up builds online. What bugs me is when I know what my next item is, I search it, buy half of it and go back in the fight but the search doesn't keep when I back to finish buying it. It takes time to type it every time, it takes time to tick through the boxes and look through the items, and sometimes seconds are all it takes for the base to go down.

So please either cut paste this feature or make the search be saved for the next time I open the buy menu.
