Per-exercise weight unit setting for tracking

Hi! I have a feature suggestion that I think would improve the workout experience.

Currently, the default weight unit (kg or lb) is set globally in the app settings. However, many gyms have a mix of machines—some display weights in kilograms while others use pounds.

It would be really helpful if the weight unit could be saved per exercise instead of only as a global setting. That way, each exercise would remember whether I logged it in kg or lb.

Right now, I have to manually switch the unit every time I use certain machines, and when I start a new workout from the same template, the unit resets back to the app’s default instead of remembering my previous choice for that exercise.

Having the unit preference saved per exercise would make tracking much more convenient and prevent accidental logging in the wrong unit.

Thanks for considering this feature!
