Is there a way to see how many games you have with a champion?

Right now, the only method I've found was to go to my Match History, pick the champion, scroll all the way down, press F3 and search the champion's name to see how many games are registred. However this only works if you started to play that champion after 2014. Seeing as I've been playing league since season 2, this doesn't really solves my issue.

Anyone knows of a better way?
