Pool Swim - Total rest time?

Tried pool swimming for the first time last week with my pace3 and really loved just hitting go at the start and all the lengths, rests and total distance being tracked automatically.

One slight gripe, why can't I get a total rest time anywhere? At the bottom of my activity page it gives me a "total time" and "activity time" but they are both the same because I didn't manually hit pause.

On my bike I have auto pause set for stopping at traffic lights so when I finish a cycle I can see my total time (with pauses) and see my activity time (without pauses) and can do a quick subtraction if I want to know how long I was auto paused for. Can I not make swimming behave that same way? Otherwise the "avg pace" stat feels a bit irelevant without the context of knowing if I was going faster because I took more breaks etc.
