Fireworks CS4 - Editing the size of the background of an animated .gif without changing the size of the sprite

Question

I have an animated .gif which I'd like to modify. Specifically, I'd like to be able to make the background/canvas slightly larger without it affecting the actual animated sprite. Is there a reasonable way to do this in Adobe Fireworks CS4?

Thanks.

Answer 1

Found the answer after a bit of trial and error. Fireworks allows one to change the size of the underlying canvas without affecting the layers on top. Worked perfectly once I found the option.
