elevation benchmarks

[wvancampen]

As I understand it, when elevation benchmarks are set relative to a reference elevation (say in a section viewport), when you move the viewport all the elevations change. And when you set them to a control point, when you move the benchmark the control point moves with it. Is there some way of doing what I would consider most logical and useful: benchmarks are set to some reference or control point, and when you move them (eg after you change a floor level)--the elevations would adjust. Or another way of putting it: behaving as reference elevations do now, but would not change when you move a viewport?

You have described the tool perfectly. I know of no way to do as suggest in the end.
