Template creation

Hi.

I'm using PowerCivil.

Here is the issue. As in the sketch below - black and red are two superelevation cases - normal and elevated. When elevated (in red), I want section 2' to be the same slope as section "2" and stop at he ditche's outer slope. I surely know how to do this in case 1' follows section "1", but don't know how to do this for the elevation stage.

Woukd appreciate any suggestions. Thanks.
