Rheotomic surfaces + Geodesic dome

I made this Geodesic dome with points projected to the xy-plane. I would like those projected points to become Sources for the Rheotomic surfaces algorithm. Only Sources, and no Sinks if possible. Is there an easier way than to select each point individually with list item ? And also; how can i delete the Set Points for sources and sinks ? I don’t need the old ones anymore, they don’t match with the projected points from the Geodesic surface.
