Champion Select Custom Search

I'd like to see something like item sets implemented into champ select like how you can type marksman into the search. Being able to make a keyword for a custom search of the champions you've selected to match that keyword would make it easier since some champions we play in roles that aren't what their classified as, like Morgana who isn't considered support in her role, or so you could search main and pick from all that champs you're good with.
