Role Organization using search bar

I think that when you are in Champion Select or in team builder and you have the choice to search, its great. But to make it better, i think that before u go to search, you have to go in something like "Item Sets", where u, instead of making optional builds, you can set each champion to have a specific role. its like when u type in marksman, all the adcs come up, but instead of that, you could type in top, or mid, or support, and the champions that u selected to be in the specific place, should pop up. I just think everything would be easier during champion select. Just a suggestion, tell me your thoughts.
