Station Numbers may be edited by the user. When a Station Number is edited it becomes the reference Station, and all other Station Numbers are recalculated based on their distance from the reference Station. There can only be a single reference Station at any time.

This recalculation is performed when the edit is a valid numeric Station number format (e.g. #+##).

Invalid entries are allowed (e.g., "Start"), but will not cause a recalculation of other Station number values.

The order of features in a profile, and their Station Numbers, may be reversed using the Reverse button.
