Feature request: notes on stress/HR timeline

I am keeping an eye on my heart rate and reported stress levels with Garmin Connect. I am trying to spot patterns of when I have low HR/stress or unusually high. 

It would be useful to add notes to the HR or Stress log for a day, or, even better, long press at a time (which you can already do to see your HR or stress at a particular minute) and add a note there.

I know lifestyle logging exists, which sort of does this, but it's not free-text, so I can't say something like, "had a stressful meeting 10-11am" or something.
