Photo AI needs better granularity

Photo AI needs more granularity. By this I mean each AI setting (denoise, sharpen etc) has little (to my knowledge) adjustment. As such I almost exclusively use the original Denoise AI and Sharpen AI to improve my images.
Both Denoise AI and Sharpen AI need to be able to negatively mask the subject (ie subject masked or that selection inverted).
Finally it is outrageous that I paid for a years maintenance/improvement of Denoise AI and Sharpen AI and Topaz delivered little or nothing!
