Stress Level Notifications

I would like to be notified every time my stress level reaches a certain threshold (e.g. 70 or more for 5 or more minutes).  I would use this to remind myself to slow down and maybe breathe/stretch for a few minutes to break the cycle.

Ideally, Garmin would build this into the watch as a feature.

Alternatively, as a developer, I'd be happy to develop this functionality as an app but I don't think the SDK currently allows this (i.e. I don't think I can have a background app that's notified on such stress-related events).  If anyone has ideas, please share.
