Suggestion: Please let us see which champions available in champ select have earned a chest already

When looking at your own profile, and seeing champions you own, you can tell which champs have earned a chest by the box around the icon.

Please add this in during champ select, so that we can easily tell which champions to choose if we have a chest available! Hopefully not too difficult, and would be super-helpful, as opposed to constantly consulting my champs list before entering a game, and then promptly forgetting who can still earn a chest...
