Photo AI ability to store slider settings/default sharpen

The sharpen dropdown has strength and clarity sliders, which are great.However it would be good if

a) one could select settings suitable for their work and store these as the default.

b) For a particular job, where a few very similar images will need the same settings applied, a way to store user presets, so the same settings can be painlessly applied to successive images.

The above may be currently available, but as a new user I have not yet discovered them!
