Be Able to Change Summoner Icon while in Champion Select

I just think this would be a good thing to add to the game and that it wouldn't be that hard to do. I have summoner icons that I like to use for different champions, including icons that are specifically for a certain champion or line of skins, but sometimes I change my mind and go with a different champion in champion select. I know it's not a big deal but I think it would be nice to be able to change the icon while in champion select.
