Hi Don,
If you don't want to reinvent the wheel, then....
In Gold, you have to do this in two slides and not just one
The first slide contains the movement up and the second slide contains the movement down.
All you need to do is simply to "continue" your movement in the second slide, precisely from where your first slide stopped - that is - at the top of the slide, where the layer "jumped".
The only difference between the two slides is in the order of your layers: the layer that is underneath in the first slide, changes position in the second slide and becomes the first in your second slide. A layer that is first, can "jump over", all the others, as you said. This is the trick
If you place a 0 (zero) time transition between your two slides, the whole animation looks as if one movement.
But, this effect cannot become a style, because a style contains all the movements of one slide only, and this requires two slides. These instructions are for Gold. In Producer things are quite different
Hope this helps.
