Can I create tournament with GameLift?

Hey!

So I’m working on a match based game with 1v1, 2v2 and 3v3 modes. I’m making this gane with the help of GameLift and I would like to add tournament mode later. So my questions are:
-Can I make torunament mode with GameLift?
-If yes, Could anyone give me some advice with that, how can I do it?
