Tween back to original position?

Do you know how to rewind a tween. but I dont want it to just snap back to the beiginning. I want it to yoyo back to the beingining without actually yoyoing many times. you know what I mean?

this is the code I have which make the beginning motion I want:

public function imageSelectR(e:MouseEvent):void {

myTween = new Tween(imageLoaderHost, "z", Regular.easeInOut, 0, -100, 1, true);

myTween.addEventListener(TweenEvent.MOTION_FINISH, imageSelectL);

public function imageSelectL(e:TweenEvent):void {

myTween.????();

//what goes there?

}

Thanks for any help!
