"Roles" icons in Champ Select

Have you guys considered to change the role icons (on top next to the search bar) in champ select to groups we can put together ourselves? It kinda feels like it doesn't quite hit the spot for what it is meant for.

For instance, I'm a support main, when I'm in champ select and looking at what champ I am gonna play, I usually press the Support icon button in the top. When I feel like playing a heal/shield support I usually forget about Karma because she is listed as a Mage instead of Support. Also for Top and Jungle there are many different roles you can play, but there's no button to have a complete view for the champions in a specific role.

If we can put together these groups ourselves we could have a better view of our possible champs to play in a specific role than how it's currently working. For instance I can put Zyra, Brand, Morgana, Karma, Alistar, Blitz and Leona on the support page. Also someone that mains Top can put Shen, Swain, Darius, Irelia, Pantheon on one page.

It's just a thought. Not sure how many people actually use this, but I do a lot.
