Workout notes functionality

Does anyone know if FB plus has the functionality to write notes for individual workouts, outside of the calendar notes? If not, would anyone else be keen to have this functionality or is it just me?

I modify certain workouts to suit the way I like to workout, and I like to see how my weight selection has changed over time for the workout video. I don't want to find when I last did the workout in my calendar to find my calendar notes for the workout, so thought workout notes would be useful.
