Custom Tags For Champions?

So with my champion pool slowly growing and the play styles I like to utilize increasing, it's come to the point that I want to be very specific in terms of what I want to do. Maybe I want to play an AOE CC Champion to help my team during team fights. Perhaps I want to use a champion that I deem good for early, mid, or late game. Break out a list of knock ups for a Yasuo on our team maybe. I just think it would be a great use of the Search Bar in the Champions Tab/Champion Select. Like, instead of only looking up names and roles, I can go through my champion pool and type, say, "AOE CC" into a given champion's custom tag. Now whenever I need it during champion select, I can simply use the Search Bar for that sort of function; finding champions with AOE CC. Or, more personally, I like trying out oddball Junglers from time to time. Maybe I can type down "Jungler" into the bar and it will give me a list of all the Junglers I custom tagged with "Jungler" for champs that I can get through their first clear with.

Just a smallish quality of life change I would greatly enjoy.
