Does anyone know of a way to continue connection lines when placing new center marks on different holes.  When I place multiple center marks and have the connection lines button checked all of the parallel and perpendicular holes automatically get a connection line between them.  The problem starts  when I stop placing center marks and come back to it later and want to continue, or if I add a new hole to the part. 

My workaround now is to apply a second center mark to a hole that already has the connection line and start back up again.  It seems that there should be an eaier way to continue the centerlines.  The only other option that I have found was to remove all of the center marks and start all over.
