Quite often workouts have repeating free ride sections where you should aim for the same power or more than previous.
When a long wanted lap button is not yet there how about an extra column to workout sections → realization…
That kind of already exists for couple of climbs f.ex Alpe du Zwift…
It would be useful also other than just for those repeating phases I think.
Sorry about my really bad picture 
but in case that text does not tell what I mean
