Is there a way to reset YAW in PC mode?

Using these in warudo and over time tracking drifts a bit and my YAW needs to be reset so I am facing the camera. It seems there is a button for this in VR mode, but is there a way to do this in PC mode?

Additionally - is there an API I could call to invoke that so I could connect it to a stream deck button?

Not currently, but development will follow (expected within two months), though it may require maintaining Apose. Alternatively, we may wait for an upcoming upgrade; the current gray-scale test version shows significant performance improvements for the 6-axis, allowing it to last longer.
