Idea for Riot - Champion sets (similar to Item sets) to categorize your own champ pool

Maybe this is just me, but there are a lot of times where that clock is running out to pick a champion and the only thing you can think of is your 1 or 2 top champions you play all the time, even if they don't fit the role you are now needing to fill. I don't want to always play those champions but by the time the team selects where they are going and fight for whatever spot they want to go, you are left with 10 seconds to pick an AP jungler to fill the gap in the team.

What I would like to see, and think it would be really useful, would be if riot gave us the ability to create Champion sets similar to the way we create Item sets. Basically a folder for each style/lane you want and put the champs you personally find viable in that folder so that if I suddenly need that AP assassin jungler, I have a champ set folder for that so that I can click that folder and see the 3-5 champions I put in that role rather than having to scroll through my 100 champ list to hope I see one that fits, only just to forget that Diana is a decent jungler, or that elise can be build damage and not just tanky, etc.

I've even looked for Iphone apps that might have this capability and have yet to find one. (If anyone happens to know of one then by all means please let me know as I have many friends that would like this feature as well and I have been searching for quite some time on a way to best have this filtering capability).

Granted this is a rough idea, and not all thoughts and issues have been thought out and I'm sure there are ones I missed, but I know quite a few people that would be on board for this and I don't think this would be a huge task for riot to put it in. It's essentially a dynamic champ filter that you can personally customize.

Please give me your thoughts and take the poll below and maybe it will give Riot another good idea to add to their list.
