An idea for Champion Select

Hello fellow Summoners and Rioters!

So, I had this idea for champion select that I think would be pretty helpful. So, basically when in champ select there could be two drop-down boxes. One of them being Primary roles e.g. mage, tank, support, fighter, etc. The other being lanes, maybe? Like say you select jungle and it'll show you all the champs that are eligible jungle-ers. And then same with the primary roles.

So basically what I'm saying is what we have on our profiles in the Champions tab I think it would be a helpful tool to have in Champion Select for if you last minute have to pick a champion for your lane and you aren't TOO familiar with that lane/role or even if you have a lane/role picked and don't know who to play. Anyway, thoughts?
