I shoot astrophotography on a converted Nikon D800 with the hot mirror swapped for a clear filter, leading to a very specific issue concerning white balance with raw files. Adding infrared to the red channel shifts tint toward magenta and temperature much warmer. I can correct the magenta tint, but with Lightroom Classic's temperature slider stopping at 2000 K on the cool end, I wind up with this result (temp at 2000, tint at -106). I realize I can use an external editor to correct this, but since I often shoot astrolandscape time lapses it would be much easier to have the ability to correct the color built into Lightroom Classic.
See the later posts in this feature request:
They describe two methods for getting a white balance suitable for infrared photos: Use the free DNG Profile Editor to build a custom camera profile, or make a creative profile.

This worked well, thank you!
For others who find this through search, there's a more recent walkthrough here that was quite helpful to tie the custom camera profile into Lightroom Classic: https://robertreiser.photography/proper-infrared-white-balance-in-lightroom/
I do still think expanding LrC's native white balance range without having to resort to a workaround would be very helpful for others in the future, as the popularity of converted cameras for astrophotography in particular seems to be growing.
