Champion Select Filters

I often wish i could categorize my champions in "top lane champions", "support champions", "mid champions", etc.

when i'm in champion select, and i get top lane or something, i want to type in the search bar "top champions" and have all the top champions appear on champion select.

so far, as far as i know, the only role you can do this for is ADC, by typing in "marksman" in the search bar. wouldn't it be nice to have that for all positions? or better yet, make custom search tools for champions you want.

like custom items, make a custom champion page, like "my current mid champs" and leblanc, viegar, galio, morgana pop up and i can easily decide who i want to play from those 4.

just a suggestion that i've wished for a long time in league. please let me know if u agree or not :)
