Can you in a given discipline (running, walking, swimming, etc.) add a menu in which you can automatically turn on the heart rate, oxygenation during activity. I do not need to measure my heart rate around the clock, it is unnecessary battery and diode consumption. I need to have a heart rate measurement, oxygenation only when I turn on a given activity. Please change the menu of each discipline and there in the submenu add the option to select which options from the watch are active during this discipline. A simple solution that satisfies everyone, so simple and as you can see, it is so difficult for you to implement it.
I see that the community has not been able to ask for it for years, can you really not do it?
Please keep this change in mind for future updates.
