This is pretty specific and niche but I think being able to link factors together would be helpful. So factor A would only apply when factor B applied.

For an example: Two of my factors are work from home/going into the office. Another of my factors is bring lunch to work. I am happier when I work from home, so it appears like bringing lunch to work makes me less happy. But that’s presumably just because I’m going into the office. What I want is for bring lunch to work to only apply on days I’m in the office, so I can compare whether bringing lunch in has an effect compared to not bringing lunch in.
