Don’t know if it’s possible but can you use a USB shutter control with SGP, idea is that you could use an unsupported camera, like the D810A or older camera’s just with a USB shutter release cable.
The benefit being that you could do dithered imaging runs and even mosaics …
(though no plate solve and focus would be available, but at least you could use the camera …)
So is this possible or if not it would be a feature request …
