How to generate a missing profile?

I am in the process of upgrading my DLSR setup from a 5 year old Canon 5D to a higher resolution body. I have tried two:

  • Sony A7r IVa
  • Fuji GFX 100s

And both of them show up with “Missing profile” when I try to use Negative Lab Pro. As I understand it, I have to wait for future NLP updates.

Is there a way to generate profiles for these cameras?

Is there a way to force NLP to use the profile for A7r IV (without “a” prefix) because it’s the same camera?

Thank you.
