Independent UIs for multiple Players

So, I am wondering if it is possible to create two independent UIs in the same scene, say one on the left and one on the right side. Then treat those two independently, so each player can navigate his own UI with their own controller. I assume that this is going to be a bit difficult, out of the box, right?

You might have to do your own controller navigation, but I’d think creating two separate UIs would otherwise be easy.
