Any way to combine masks in LRC 11?

[Dave Rye]

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!

And yes, you combine masks, create a mask, Add or Subtract, or Intersect.

Speaking of intersect:

oh, and yes, you can copy a mask, and you can invert a mask.
