PowerCivil SS4 [.789] - Tool request, Vertical variable offset

Hi.

I am looking for a Vertical Geometry tool that does the same as the Horizontal tool "Variable Offset Taper". Is there some tool that I have not yet found which accomplishes this task?

In the picture below, the bright green line which follows the terrain is what I am looking for. The vertical offset from the terrain is 2.5 m at the start and 2 m at the end. As you can see, I had to go via "View 3D Alignment tool" to get what I wanted.

I have also tried to illustrate what I want in this video.
