In SS2 and SS4 you can edit a single station template. Doing so you are working on a single station and in the template view and design is updated accordingly.
Another way is to edit features in SS2, but unfortunately you can override the changes if you run the corridor in the same zone.
In SS4 you can control points using linear geometry and change the linear geometry, but it is not like changing the template: you don't work on a cross section view (you can also do this in SS2 with feature). In SS2 changing the feature also change the component.
In SS4 it is much more easier also to mix design using corridor and other methods (linear geometry, surface templates, linear templates), you may find an appropriate workflow.
But as said at the beginning, you can edit a single station. In SS2 by a double click on the cross section view of the Roadway Designer, in SS4 by using the "edit station" from the cross section tools in the corridor modelling task.
