Suggestion : Sort by Region/Nation for Champions

Nexus blitz is active, and some of the missions require you to pick a champ from a certain Nation, or whatever you call it. i was wondering if it would be possible to add the option to search what champions are from where, because i was kind of drawing a blank when trying to remember where everyone hails from.

I know there are multiple ways to search that information outside of the client, and you can do that from league website directly if i recall , but i was thinking it might be a cool little idea to have in-client , so you can look it up while you are getting situated .
