Would it be possible on the Turing Smart Screen 2.1" to have the 90/270 degree options in the orientation field?

Because the 2.1" screen has square themes, the "DISPLAY_ORIENTATION" in the theme has no meaning, and the orientation should be set directly from the Configuration window: instead of the "classic/reverse" Orientaion choices, there should be 0°/90°/180°/270° options
