Copy selection from once anhancment to another+invert selection

Hi. i work mainly with pictures of people genrated by 3d software, i have problem with noised hair so use Photo AI mainly to denoise them but as i do not want to blur all picture i manualy select area of denoising, and then sharp picture a bit but not that dnoised hair, so i have to select all and then manualy deselect hair so i spent so much time on that thing. it would be awesome to alow me to copy selection from one enhancment to another and then have function to invert selection. it seem that it should be very easy task for you guys to do such a thing.

Also nice thig would be also to select hair only in Auto selection option (like for subject , environment etc).
