Can we please earn tokens from Game Modes?

Title.

So since we can get Mastery grades in game modes, is it possible that we could earn tokens as well toward our lvl 6 and 7 mastery badges? I just had a great game as Yorick in Hexakill going 11/0/22 and got an S, but got no token. I really want my lvl 7 Yorick. >.<
