P: (Masking) Select Landscape Constituent Components

What adobe has done for masking people where it allows you to select people and then sellect the person/orpeople and check the boxes for different parts to create seperate masks is fantiastic. I think it would be really helpfull if the created something similar for landscapes. It would be most usfull if it did sky-highlights-shadows (Seperate masks). Mountains-highlights-shadows (Seperate masks). Ocean-highlights-shadows (Seperate masks). Rockface-highlights-shadows (Seperate masks). Seastacks-highlights-shadows (Seperate masks). Lakes-highlights-shadows (Seperate masks). Windmills-highlights-shadows. Roads/tracks-highlights-shadows (Seperate masks).
