Please add the interval power range to the workout data,
if it specified one when creating the workout.

On/off in the setting:
UI Setting > LEFT > Workouts
Power range (show all power range for intervals)

If I'm creating a range-based workout (not a target) and would like to see the entire range in the workout data while riding. So, I can turn off the EGR and ride using the entire range, not just the middle.
