Predefined layer with style and luminance selection

Hi,

It would be great if I could save predefined luminance selections in a style and add them to an image by pressing a key.

The way via "new filled layer" + "luminance selection" + "set selection" + "add style" is very long.

Saving a stack of layers with styles and different states of opacity into a style would also be useful.

Kind Regards
