Practice tool optimization.

Greetings summoners, ill start off by saying this is the first thread i ever wrote in my 5 years? or something like that playing the game, so i kinda hope it'll be heard ^^ Its gonna be a short one, there's a very obvious optimization that can be made to the already existing practice tool. See, you can change your items at you will and that's great, it allows you to test out different build paths against the dummies and try for combos and see which does more damage. But what comes with itemization are the runes you pick, i think we should have the option to change the runes of our champion without existing and entering a different practice tool instance. That way we could test and item set with its rune set, check out the damage and combos, then quickly switch out to a new set of items and runes and compare the two. I think that would make the practice tool a much more user friendly tool to help people try out new builds and try out their combos. Thoughts? PS : Didnt know if that should go under gameplay or general discussions, if i posted in the wrong board please let me know.
