Look in the Pong V9 video. If you see when the projectile hits the black it whiches the print to a new #. I think this is done by a simple event like Wait for: Shot>Print:list:# and the wait for is triggered by a color senceitive projectile. I am not 100% sure and this is all gotten by looking at the video. I am not a beta tester. So if one would like to tell please go ahead.
