Tracking of custom values

Hello everyone,

i would find it very helpful to be able to

1. Create new custom values (e.g. Blood-pressure, merit, etc.)
2. Add values every time you measure (like for example the body-weight)
3. View graphs for tracking the behaviour throughout longer durations

This way i could track other health-related values, keep being aware of bad conditions and maybe see dependencies to activities/fitness for my overall health-tracking.

For me it would be the same as body-weight-tracking but for different custom-created contents

Thank you
