I'd like to create custom workouts like TPv default ones, which fluent ramp-up warm up phases. This seems not possible in the current workout builder. To do this with the given ramp-up option I need at least 5 steps, which seems cumbersome for configuration.

Unfortunately, TP workouts are a lot less sophisticated than Zwift but I'd like to give TPv more chances. Having a fluent ramp-up option in the workout builder would be another missing part in the TP ecosystem!
