Combing raster mask with drawn and/or parametric masks

[Duke-of-Sound]

Is your feature request related to a problem? Please describe.

I frequently take pictures of wildlife. During the photo editing I usually use a mask to isolate the subject wildlife. I additionally add masks to give the photo depth etc. Under the present build as I understand it, I have to redefine the subject every time I add more masks to improve the photo.

Describe the solution you'd like

I would like to have the ability to define the subject once and have it saved as a raster mask. Then I would like to add that raster mask and combine it with additional masks to improve the photo. For example, combine it with a gradient mask to provide depth, or combine it with a parametric mask to select a portion of the subject for further editing.

Alternatives

An additional approach would be an ability to have a one click approach to select the subject.
