Intensity / HR Zone time data fields

[eduardodfj]

Hello.

I just bought a Karoo 2 but I'm missing some kind of intensity data field for those of us not using a power meter. With my previous Garmin, I was using Time in Z3 and Time in Z4, which I could substitute for others (TrainingPeaks' or Strava's Stress Score) if available, but I need to know how much effort I've put at any given moment in my ride.

Is this available/possible?

Thanks.
