Is it possible to create 4xspeed game, or do i have to wait for an event

Is it possible to create a game with 4x speed, or is that only available during special events? Me and my friends would really like to play together, but we don’t really want to queue with random players who are much better than us. It would be a lot more fun if we could just set up a 4x speed game ourselves and play as a group. If that isn’t possible, do you know how often these events happen or when the next chance to play at 4x speed might be?
