Pool swim pacing alert. Reset or auto reset...

I have been using the transferred Garmin Swim 2 functionality, swim pace alerts, and I really like it.

I configured it to beep/buzz for a pace of 1:35/100 m in a 50 m pool. And that seems to work fine. If I am correct though, the timer is independent of if I make the pace or not.

When using a so called tempo trainer, there is an option to reset the timer, so that I can start over again if I am behind my pace/beep. There seems to be no such option, or am I missing something?

I guess there could be two options, one where you can push a button the reset the timer or a setting where the timer reset it self every time you turn around.

Anyone else here using these features?
