Unfortunately there isn't any way to draw a line between a centroid and an atom. Instead you would need to add an atom at the centroid position, then measure atom-atom distance (which is shown as a line).
You can add an atom at specified coordinates using Build Structure (in menu under Tools… Structure Editing), Start Structure section.
Centroid coordinates are reported in the Reply Log (under Favorites in menu) when the centroid is created, and can be written to a file using the Save button on the Axes/Planes/Centroids dialog.
