Rotate unPhone screen?

I was wondering if there was a straightforward way to be able to rotate the unPhone’s screen? I’d tried using setRotation from the adafruit gfx library, and while this would rotate the display it would also mirror it in weird ways (ie drawn text would be backwards) which I couldn’t figure out how to resolve.

P.S I’m using the unPhone 9 and building off of the ‘everything’ example, so had been trying to do this rotation in unPhoneUI0.cpp
