Custom Champion Sorting Idea

Ok, I'm the first to admit this would be a MASSIVE programming undertaking, but if done well, could really help in champ select.

So first, the idea (thoughts behind it to follow).

Pretty simple, just as we can create item sets, let us create our own custom champion lists. It doesn't even have to be lane specific (I.E. dynamic cue puts you in top, so a top-lane set appears). We can sort it how we like. Tanks, CC, crits, tank shredder, poke, mage, assassin, however we'd like to sort them, and create multiple lists just like item sets.

The thoughts behind it are pretty simple.

Maybe it's just me, but sometimes, I forget about a champ that may fit the role I need. I need/want someone with a lot of DOT damage, and I forget about Cassipiea. Or I want some lock-down with CC, and I forget Lissandra (I swear, I cannot remember she exists). Or I can't think of the best tank-buster ADC for the situation. With a custom set, instead of sifting through the entire champ list, I can go to my "tank-buster" list, and sift through those instead. Even the ease of sifting through mid, or top, or support champs would be a big help in being able to adapt on the fly. It's not just finding a specific champ, it's thinking of them for the situation at hand.

Again, this would take A LOT of work to do. But if they could, it would make champ select so much easier.
