Currently there is no way to use end condition exceptions and as an override switch between other end conditions within a certain station range. A simple addition to the override feature where you could temporarily change the priorities of the end conditions within a template drop would be nice within a station range. I know some of these such as simple fill slopes and cut slopes are easy to do via the override tool, but more complicated end conditions with ditches would be nice to achieve without having to redraw the elements entirely within the editor.
