Hi Martin,
Sadly no. Blender will pretty much do what you tell it to do (most of the time).
So when you have all the bones selected and you calculate, it’s going to calculate all the selected bones.
I find myself clearing the cache and recalculating when I need to, but I have those functions added to my quick favourites. This can save a bunch of time.
Also I find myself using ‘around frame’ rather than ‘in range’ a lot more these days, as it keeps the view cleaner.
Hope that helps.
