Wrap Solidify segment editor effect for filling smaller holes

I just saw the youtube video about the Wrap Solidify effect, very nice work!

I’d like to ask about its potential usage to fill smaller holes. Looking at this screenshot, I can see that there is a Custom region mode, which allows selecting one of the segments. Could this be used to segment smaller cavities such as the soft bone area in the mandible, like in this screenshot below?
Thank you!
