Organizing champs in champion select?

Just an Idea.. I cant count how many times i went to the bathroom, then came back and it was my turn to select a champ, and i couldnt find him/her in time. I thought a great idea would be if you could organize your owned champs into folders. For example, top, mid, supp, adc, and jg (depending on who you like to take to those roles. I like ezreal mid more than ez adc). So yeah, this doesnt seem like a very hard task for riot, so please make it happen!
