Totals & Averages for all intervals

Did a search and could not find this topic mentioned earlier. Sorry in advance if it is already a featured request.

Pls see the attached screenshot from my iPhone. I would love to be able to see totals and averages for my interval workouts. Possible?

Another thing is when I do 45/15 seconds intervals the 15 seconds rest are listed as work, but they are actually recovery. I guess the heart rate is relatively high so they are automatically picked up as work. Now I select and delete one by one. Possible to select multiple at once so it is quicker to delete them?

In advance thanks.
