As far as I know, you can't move or progressively alter anything while a
visual effect is  taking place.  The best you can do is create your own
visual effect, which in your case might be to create a group that expands to
reveal its contents.  You can also use image objects as masks and
progressively set their blendLevels to hide or reveal objects beneath.
Alternatively, you can progressively resize an image or graphic from a tiny
dimension to full size.

Each of these options requires that you roll your effect/timing, but it can
be done and it's not terribly hard.
