Champion lane Builder (for draft pick)

We all know that you can build item sets but id like to see an upgrade that lets us set champions to a lane and in draft pick we add a buttion for every lane that you can click that sorts out the champions you put in that lane (just like item builder)

This would be useful Insted of searching through all your champions when your the top laner you could just hit the top button and boom all the champions you have registered for top lane show up So you dont have to scroll through your pool to find who you wanna play. Or if your supp you click it and all your registered champions for support show up its just 5 lil buttons each with there own lane symbol. I think should be added to the top left of the draft champion pop up page as there is just a blank spot there
