Magic move - force object matching

In PowerPoint with the Morph Transition, you can name different objects with the same name that starts with !!, like "!! Object 1" and "!! Object 2" and as long as you use those names the same on the next slide, when you use a morph transition, it will force them to 'morph' or at least move to the correct positions on a slide while they cross dissolve. The !! code doesn't seem to work in keynote and I can't find anything in any of the support documents. Does Keynote just not have this feature? Or any thing similar? I'd love to have a way to do it within Keynote, rather than having to use PowerPoint.
