If you read this and are interested in having this function, please reply.
We need the ability to put a slope mode (non erg) interval into a structured workout. A quick Google search indicates people with all models of Edges capable of controlling a trainer are asking for this feature. Maybe we are not asking in the right place or to the right person.
This is a fundamental need when using a smart trainer. Erg is great, but in many workouts, an interval(s) is needed with a constant / non adjusting resistance point.
