Shared Object & Children

In a nutshell I’m adding duplicates of the same child when the user clicks on “addBtn”. How would I use SOs to save the children that have been added?

Cheers

My code:
var container_mc:MovieClip;
var juryMC:MovieClip;
container_mc = new MovieClip();
addChild(container_mc);
addBtn.addEventListener(MouseEvent.CLICK, onAdd);
function onAdd(evt:MouseEvent):void {
juryMC = new jury();
juryMC.x = Math.random() * stage.stageWidth;
juryMC.y = Math.random() * stage.stageHeight;
container_mc.addChild(juryMC);
}
