Is there any way to combine a set of masks in LRC11 into one? Such as if I select the subject, then brush in sections missed by the initial try? If so, will I be able to take the combined masks and ask for an inverted section to the result? That would let me add/subtract from a subject or sky mask and then invert that to change the saturation or exposure in things not as significant in the whole picture. That could be great!
