I get what you're saying. As far as I've seen and tested (cause I was also curious), the C based boards don't auto-adjust cold ohms. It'd be pretty slick, but it seems that manually measuring is the way to go. I do it fairly often, especially since outside is almost always vastly different than inside round here.
I use a specific profile for a given atty cause I switch up all the time. I always keep the ohm lock on with TC coils and do a manual measurement when everything is at at a stable "cold" temperature. From there I don't need to touch it and all is well. It works for me at least 🙃
