Can we have an indicator of which champions we've already earned hextech loot for in champ select?

Sure, we can check it out of game via the champion roster we own but unless I start keeping a list of who I can play to be eligible for, say for example, key fragments (I'm maxxed out on chests, like many other people), it's a little tiresome when you see you or a teammate has gotten a form of S ranking...only to get nothing from it because you had forgotten that X number of games ago, you played Y champion and a teammate got an S.

Just put a little notice if we hover our mouse over them or something.
