I am not sure if this is what you were talking about tthunderdan, but if you want to exclude some versions from your animation, set the amount of frames you want that version to show to zero.

Here I set version two and three to zero frames and they don't show.

Not too helpful on editing old versions, but at least when you see something that doesn't look right, you can start redrawing after the frames you want to exclude.

...that should do it, I imagined there had to be a way...now I have to think (smell rubber burning?) of a draw and try it, thanks very much...
