Answer to my question is yes? is this correct? And I would specify the label under the sideshot traverse drawing settings or under the curve/spiral tab. In this case the the box is checked for showing rays, and the label for the rays is ghosted out? Suggestions?
Another option in the meantime would be to have the Horizontal Curve dialog box create the radius point and then recall it as sideshots from the PC and PT of the curve and have the traverse draw and label the radial lines.
