Small Suggestions Regarding Available Hextech Chests to Harvest

Could we please have a small indicator somewhere in the champion select screen for champions that either we have or have not yet collected their hextech chest for the current season? A lot of the time, I'll want to change which champion I am playing just because I have yet to secure a particular chest, but I forget and can't always remember to check my profile before going into games to memorize every single champion I haven't picked up a chest yet for. Anyway, that's it, thanks.
