Sorry, if this ended up in the wrong place, but out of all the wrong places, this seemed the most "right". Also sorry if this already been suggested.

Im a rather casual player on and off, but for my idea I think its something everyone would enjoy.

Heres the thing: I often lose track of how my item build was when returning to an old champ. I would love to have the option of tying an ingame shopinglist to my champs. Like a little list in order of how I normally would like to buy my items.

How this exactly would be done I leave completly in the hands of Riot of course, but such a feature would be amazingly helpful to me at least.
