    AFAIK you can only have one extends="scene" component.
    The component element requires 2 things -- a unique name, and "Extends" - The name of the built-in node class, or extended component, that the component extends
    If you want multiple screens, use extends="Group", or extends="Task", or the name of the node is based upon for your modifications.
