Trip Meter and stop watch access

Appologies, should have been  posted in discussions- please ignore this post (can't see how to delete it)

I am trying to build an app that includes some distance trip meters.  My plan was that I could use the in built Garmin stopwatch app for one.  I found the setTimerEventListener under Toybox.ActivityRecording.Session but it doesn't look like I can use these to start the timer.  There seems to be other discussion supporting this, am I correct in assuming I can't use this?

for a second, I was hoping to be able to reset trip data from within my app.  This also doesn't seem to be a part of the SDK, am  I wrong? 

I seem to be finding the connect IQ platform a lot more limited that I expected.  With no access to internal timers I don't see anyway of doing my own distance trip meter.

All advice appreciated!

Thanks
