I'm afraid only the defaults are available. What look are you trying to
achieve as someone may have a workaround? For example, you could use a
custom animation fade out of a picture of the end state of the old slide, at
the beginning of your new slide.
i just delivered a presentation that had 183 images on a single slide
because of this. Your only options is to put your stuff on a single slide,
or get a screen shot of your next slide, dump it in and try to fake it.
