I just wanted to let you guys know that I spent some time today, and found an undocumented feature that can be used to achieve the desired effect. I'm quite pleased by this too, since I think this was a significant downgrade from 2020. I'm going to use it as an excuse to write some scripts to help me manage the lighting effect files for MSFS 2024, because they are so numerous, and require so much adjustment compared to MSFS 2020.
EDIT: Looking at the date of your original post, this actually wasn't about MSFS 2024. Pardon me! I just like to let people know when I've looked into their problems and found solutions.
