Preferred Role Option Instead Of Recently Played Icon

Interesting Idea. When looking for people to invite to play ranked or even a norm, it would be helpful to know what they prefer to play to help build a team. Normally you would have to search through their match history or make a guess based off their recently played. Im asking to implement an area where you can put what your preferred roles are, in place of the recently played champion icon. Basically when you would scroll over a friends name in the friends list it will show what they prefer to play, easing the ability to invite people who play the role you need.

Thoughts?
