Interval information for structured workouts

Hi,

I'm looking to find a way to display the current interval number and the total number of intervals for a structured workout. I would like to display the information in a form like 1/10 (interval 1 of a total of 10)

I can get the current information of the current step using the classToybox.Activity.WorkoutStepInfo but I don't find the current interval number.

Does anybody knows how to do it?

Thanks
