@stavrogin - Third party own the data that is displayed on their imported workouts on Suunto, for TP there’s this ER idea to add the step counter, feel free to vote for it.

Adding to my previous post, after disabling the auto lap, you can setup your own screens to see avg numbers for whatever metric you want and it’ll be for that step of the workout. But definitely you cannot see what step you’re on with TP workouts, until TP implements above idea.
On your question about undoing a manual lap, it’s not possible, and when doing a manual lap while executing a workout from TP or any other place, it’ll skip the current step. This is by design and cannot be altered.
With that said, Training Peaks has the best screen for executing structured works, the only missing piece is the step count in my opinion
