@Riot Choosing during champion selection

I’m pretty sure someone might of mentioned it or maybe not, but I was just wondering if you guys have ever thought of adding additional tabs during champion selection next to the "Champions & Skins" tab to help narrow down the champion pool. These tabs would allow the summoner to add whatever champions they want to that tab such as, jungler support, marksman, ap/ad mid, top etc pretty much how you added the feature to add builds. Its happened to every player either in ranked or in normals to fill a role that you didn’t jump into que wanting to play but still ended up filling. As you begin to get more champions after playing the game for awhile its hard to pick a champion to fill a specific role on “short notice” while under pressure so with the tabs it would really cut down the time looking for a choice and help you figure out what champions you play more and feel more comfortable playing within the given team comp. I really dont know how taxing it would be to add such a feature but it was just a thought.
