Collaboration message responses

I cannot seem to find a way of depicting the response to a message in the collaboration diagrams. As far as I know there is normally an arrow with a open circle on the opposite end of the arrow (the from side) by which one would signal the response on a certain message sent (which is as far as I am concerned not the same as a reverse message which is more like a callback). Is there a way to depict this in VP Standard Edition ?
