Resetting Odometer

I would like to reset the Odometer data field in my Trip Computer page.  Currently it shows the mileage for several walks (local Activity, not Tracks) since I started using this device.  I have tried the two functions (below) from the manual, but Odometer does not clear.   I cannot find any other Clear functions, have I missed one somewhere?

  • Select Setup > Reset.
  • Select an option:
    • To reset data specific to a trip, such as distance and averages, select Reset Trip Data.

    • To clear the data recorded since you started your current activity, select Clear Current Activity.

I am coming from the Explorer+, where the Odometer accumulated distance from each Trip Odometer, with the option of, any time, clearing one or both of these.  That way I could see cumulative distance from, say, a 3-day trip, but restart each day's own distance.
