Feature Requests: Create laps in my runs

Hi, I'm Alex, from Italy.

I would like to create laps while mapping new runs. I start to run from my house and after 3km I go in a park; here I run about 4  laps (2.5km each one) and I would like to edit just one time this lap by a "Start lap"and "End lap" buttons, with the number of lap as option.

Please add this feature!
