The feature definition for each profile associated with a single horizontal alignment will be the same as you have shown in your video. A single horizontal alignment can have many profiles and a vertical point control (W2 in the corridor modeling task) can be used to define a profile for a ditch or some other feature since the method of defining the point control does not rely on the feature definition. Other methods may be used but as Michael mentioned, if you search for features from a template then they need to be added as a corridor reference (T3 in the corridor modeling task).
