Force a heart rate derived power due to bad power data

Is it possible to force a heart rate derived xss on an activity? I have an activity that has bad power data (essentially zero power with a few spikes) and I’d like to use a heart rate derived xss if possible rather than guess.

The power data issue appears to be my new Garmin 530 not talking with my Quarq DZero, though cadence does show. I’m sure I can get that figured out, but in the meantime I’d like use use the heart rate xss option.

You could try to remove power data with one of these tools FIT File Tools, try “field stripper”. Import the resulting fitfile afterwards.
