Additional drop downs...

It would be great if we had an additional drop down option in Store -> Champions -> Filters and Profile ->Champions ->Availability that showed only the weekly rotation champions (maybe titled Weekly Rotation). This would make looking at them and buying them much easier and efficient. I know I practice with every weekly champion that I don't already own just to learn its basics, and that's how I find the ones I want to own next. I know there's an 'Available' option for Profile -> Champions, but that can get a little crowded once you own more than 20 champions.
