Search options in champ select

TL;DR: Make it so that we can search for specific roles in champ select (Marksmen, Tank, etc.), not just champion names.

Something that still baffles me that hasn't been implemented is easier search options in camp select. Currently, only being able to search by champion isn't enough. Owning all the champions makes select more difficult for someone in the new champ select- the number it shows is inferior to the classic select. As someone that switches up the character they play for each role often, scrolling to 'look at all my options' takes too long, especially when you're trying to counter pick an enemy choice.

Given that champions are already categorized, i.e. Marksmen, Tank, etc., We should be able to search with such tags in champ select.
