The only thing I do not know how to do with Pitbull is create a "Portrait Overlay" mode, similar to this picture: https://i.imgur.com/AuiK46i.jpg. The 3D Portrait of the characters in the Unit Frames overlays the bars in the unit frame.

I've learned from ElvUI users the feature to do so is called Portrait and enabling a setting of Portrait called Overlay. I want to know if there's any way to do this from Pitbull.
