Champion Select Filtering

So you guys are familiar with the ability to type in a role (ex: Support) in the search bar in champion select, and you filter your champion pool so that it only gives you the champions that have that role as their primary, right?

I had an idea come to me when I was in champion select last night and I couldn't decide who to play mid. I could filter assassins or mages or fighters, but I was unable to have all of my options right in front of me. I had an idea where on our main profile pages there was a tab for where we could organize our champions into the 5 positions on the map. The set-up would be similar to the Item Sets and you could choose which roles to put the champions in (and yes, they can be in multiple roles). Come champion select, you can just type "Mid" into the search bar, and the pool would filter to all the champions that you organized into the Mid lane position.

I see that this could potentially help with several things. First, it would make champion select smoother for the individual, I think, especially for draft mode. Second, it would help reduce that horrible position of panic picking when you cant find or decide which champion to play (I have often looked for a champion at the last 7 seconds and forgot to type in their name derp and panicked and picked something else).

I think it would be mostly a QoL addition, but nonetheless helpful. I would love to hear your guys' thoughts!
