How to edit datafield that comes when intervall training is starting?

I have configured some intervall-trainings in Garmin-connect and synced with the watch. Then I start "running", go to "training" and start my intervall-training that I have synced (that means I start no intervall-training that you can configure in the watch itself). Garmin shows then an additional datafield (that matchs to an intervall-training). This is shown only when I start an intervall-training. It is pretty usefull but not perfect. I don?t want to see only the heartrate-zone but also the heartrate itself. Is it possible to edit this special datafield?
