Sort Champions by Hextech Chests

So basically as we get later into the season our pool of champions that are eligible for chests are going to get smaller and smaller. At the moment the only way to figure out which champions you have gained a chest or not is by hovering over them in client before you get into champ select. Of course the easiest would be going by masteries but eventually that wont work out(next season)

Would it be possible to add a Chest category to sort our champions in client or even adding it in champ select? I think it would be nice feature to have
