The duplicated traverses are inserted directly above the original traverses. The name of each duplicate starts with the word Dup-' followed by the name of the original traverse.
Unlike copying traverses, duplicated traverses do not access the same points as the original traverses, so changing the coordinates of a point in duplicate will not affect the original.
Duplicated traverses do contain any raw data that might have been used to compute the points in the original traverses.
You might want to make a duplicate of a control traverse to test an alternate method of adjusting the points without affecting the original traverse.
