Updated survey data points

In Civil 3D, there seems to be a relationship between the points file and the points within a drawing. In fact, there is an option to reload from the points file. Is that possible in ORD? The follow up to that question would be, does it overwrite the points in the drawing?

The context for this is we have a six-column points file - Point Name, Northering, Eastering, Elevation, Code, and Note. That last column, Note, may sometimes contain text that gets put into the drawing (e.g. a symbol for a utility pole may also contain text for the pole number, and that number is pulled from the Note column). Somehow the sixth column was left off, needs to be added to the points files, then reloaded/update the points within the drawing.

Does that make sense?
