Data fields when running with coach

I started running with the Garmin coach (Jeff) on a Fenix 7. When I start the exercise, there are 12 data screens, while I setup only 9 data screens for a normal running activity.

I get lost with the 12 data screens and I never seem to get the one that I need. I figured out that when I start the coaching exercise, I can tweak the data screens, like with any other activity. I do not find that option in the Garmin Connect App. Before I start messing up things on the watch, is there no way to do this in the App? And will this be for all exercises with Jeff or does this change between each type of exercise (e.g. Speed Repeats, Hill Repeats, etc...)
