HSI heading knob and OBS tooltip

Is there any way to change the direction the HSI heading knob works? The scroll wheel moves the heading knob in the reverse direction to the course knob. I had a quick look at the HSI xml but it looks like both knobs are set up the same. Clickspots work fine but the scroll is 'wrong'. I have re-installed (twice) so I don't think its that.Also how can you change the tooltip for the OBS for nav2? Mine shows the setting for the course on the HSI. Without zooming in a lot its quite difficult to set nav2 course correctly.
