P: (Masking) Request in creating a landscape mask that Not Sky be included

LrC, please add a Not Sky mask in the mask options when creating a landscape mask. Yes, I could simply create a Duplicate and Reverse mask, BUT.

The purpose of such a mask is to be able to edit tonality, etc., for everything not in the sky. For example, Curve, Clarity, saturation, dehaze, items you may not want to apply to a sky.
