AutoCAD Civil 3D :: Section Labels From Surface Features Lines

Often we  build a design surface from feature lines and possibly a grading or two. Then we cut sections.

Now, for set out, and especially for smaller contractors who don't have fancy survey gear, it would be really nice to be able to show design surface levels in section bands BUT ONLY AT THE SURFACE-DEFINING FEATURE LINE LOCATIONS.

I am aware that we can use grade breaks...but this gives us band data at each triangle intercept which is too much data. We can weed this data, but that is indiscriminate and I really need only the data at the surface-defining geometry points (feature line locations.)

We can also use station/elevation labels on the section views but this is time-consuming and non-dynamic. Band labels are dynamic and more or less automatic...if only we could get the discrete locations we need labelled.
