Support for Canon Ra?

Does PhotoLab4 support the Canon Ra (astrophotography body)?

I tried using the DXO page to find the bodies supported, but it doesn’t show anything for Canon Ra.
But it doesn’t show any support for Canon R, and I know that is supported. So something’s not working right there.

If the Ra is not supported, is there a way for a user of PhotoLab to adjust the red levels independently of green & blue so that normal photography with the Ra could be done?

Also, if Canon came out with a R5a (astronomy version), do you think there would be any support from PhotoLab for it?
