Allow setting smallest unit of weight by exercise

Yes

Is your feature request related to a problem? Please describe.

I would like to use microloading to train Overhead Press, since 5 lb jumps have become too imprecise. I do not want to use microloading for any other exercises.

Describe the solution you'd like

I would like to be able to set the smallest unit of weight by exercise. Whether that is part of the custom template editor or some other settings panel is no concern to me, I’d be happy with anything.

Bonus would be to allow setting a custom smallest unit of weight. I have plates even more “micro” than 1.25 lb.

Describe alternatives you've considered

The only alternative would be for me to use microloading across all exercises and round them mentally, which I would prefer not to do.
