How do I matchmake into games working on DLC?

Is there any way to join DLC-focused games. And if not, why not? They added Takedown matchmaking, why no DLC matchmaking?

play with friends… works WAY better then trying your luck with the matchmaker…

Avoid matchmaking for missions… In bl3 missions matchmaking is a “random machine”. (and I still don’t understand why devs have selected this kind of matchmaking this time)
