Fanuc Roboguide PaintPro, how to simulate manual part rotation

I am trying to simulate a part rotating in Roboguide PaintPro as it passes the Fanuc robot, we have no inputs or outputs for/from the robot and the parts simply rotate 360 deg. Its a chain drive and the paint hanger has a toothed sprocket that engages and turns the hanger as it passes. Its a very simple system with a known rotation over distance, which never changes. I am trying to simulate this in PaintPro without luck. I assume its a link attached to a style, but I cannot find a way of making the part (vertically hung cylinder of 6 inches) rotate as it travels. Any help is gratefully received.
