Puzzle&Dragon-like game in UE4 ( upper combat screen need camera move )

Hi Everyone!

What I wanna do is something like “puzzle& dragon” : below is match3, and above is fighting scene. What’s more , the fighting scene is a long corridor, so I need to move the camera along left-right.
If it’s unity, it’d be easy: 2 cameras, each occupying 1 screen. But for UE4, it’s gotta be 1 camera. So:

  1. Is it possible to add other stuff in the Match 3 camera? (I guess this is OK)
  2. Is it possible to move the camera, and let the match3 & background stay static according to the camera? So it’s only the upper part relatively moving, not including the lower part.
    Thanks in advance!
