Question about PolyObject waypoint sequences

In the level I'm designing, I have some PolyObjects which use the Move By Waypoints effect, and the most ideal way to use it would be for the PolyObjects to jump back to the end instantly, instead of moving them back. As far as I can tell, there is no way to do this. Is there some way I can do it that I haven't found, or am I right that it is impossible?

Of course there is! Just rip open a worm hole that connects to another on the initial spot and guide your polyobject inside.

...Jokes aside, AFAIK there is no way to do that. :\

Didn't think so.

In any case, I have found a workaround for it. If anyone knows a way, I'd like to hear it, but it isn't urgent...the level works fine as is.

Err, I believe it IS possible.

Try EFFECT3 on linedef 488.

No, that just connects the end to the start. I'm talking about making the PolyObject vanish and reappear instantly back at the start.
