Concerning Champion Select

So I'm not quite sure where discussions about champion select take place, so if this fits elsewhere sorry!

Anyway, I think a feature should be added to the search bar of champion select where if you can type in a role and champions that are categorized under that role would pop up. It'd be helpful because sometimes I'm not quite sure which adc I want/can't look through all the options quickly if my team was slow to pick roles.

So basically you'd type in "Marksmen" into the search bar and twitch, corki, trist, lucian etc would pop up.

And if you wanted to narrow things down a bit more, you could type in "primary assassin" and then you'd just have LB and the like show up.

Thoughts?
