Tag System on Champions

I've only thought this recently, but when I go into champion select, I'm overwhelmed by all the champions I can play (since I own all of them) and cannot pick a champion in an allotted time. There's a pool of champions I like to play in ranked, but I can't seem to make a decision when it comes down to it. Which champion do I wanna play this game. Then I thought to myself what if riot added a tag system to champions. What if you could create a tag for each champion, and when you type the tag in champ select, it pops up with all the champion with the tags on it. For an example, let's say you play a pool of 20 champions in ranked. You can give a tag to each of them saying "ranked" and the role they play("top", "mid", etc.). Then when it comes to champ select, you can just simply search by searching "ranked top" and all the top champions you play in ranked pops up.

It'll be cool concept in general too. What if you added tags that says the mastery on all of them? Then you can just search up what champions you haven't hit mastery 5 or higher with and work on that. (This could be a whole different concept they could add, but the tag system could take care of it as well)

Let me know what the community think of this because I think it'll be a great thing to implement.
