Does this feature automatically add the time elapsed on a step if/when a user goes back to a step a second time? In other words is it a cumulative step time tracker or does it just track the time once?
the time continues (adds up) every time you enter the step again.
You can easily find out something like this when you just add the variable to the step, wait 5s go to the next step, wait 5s go back and see if it continues at 5s or 10s or if it starts from 0s.
in fact it continues from 5s
