Proposal- New Section to Champ Select Roles- Champion Pool

A nice quality of life change that I feel Riot could implement involves adding a section to champion select. When selecting your champion, you have the option to filter champions by role so why not add a section at the end of the line that allows a player to look exclusively at champions they have designated in their "champion pool" which have been chosen by the player on their profile (much like how item sets can be done now)?

This will make champion selection smoother (IMO) and allow a player to focus more on their preferred/good champions for league/a role rather than combing through all champions to make a decision based on team comp (ally or enemy comp) or for "counters"/combo champions that they may not be good at. Players also tend to have more fun and do better while playing familiar champions so this may inadvertently lower toxicity in games overall, but it's pretty far-fetched to think it will lower toxicity let alone guarantee it (since if a player does bad on a champion they like it'll likely make them mad/angry).

I'm unsure if this has been mentioned before, or how effective or needed it is, but I figured it would be a nice quality of life change and may help newer and experienced players with decision making in champion select.
