Add a note as a workout type
Add workout should have note as a type. That way you could see a general note that applies across workouts or health factors with ideas to yourself or coach at a high level without having to get to the specific note for a workout.

Note is currently one of the available Metric types that can be logged in your TrainingPeaks account. You can also select the order that metrics are displayed, and the first metric listed will be displayed in the Metric tile on the calendar for a quick glance. If you need more assistance with this, please contact our Customer Success Team and they can help you out. https://help.trainingpeaks.com/hc/en-us/requests/new
