Is there any way to just tell fireworks to reference another

An option is to add a Layer Mask to the top most Layer.
Select the Brush Tool, Set the Fill to Black, (optional -
reduce the Fill Opacity) in the Properties Inspector Panel, then
brush over the areas you want to 'hide' to reveal the underlying
(next) Layer areas.
Set the Fill to White, and brush over the areas you
previously painted with Black to bring them back.
This way, using Layer Mask you are preserving image data,
while the eraser tool destroys, eliminates image data forever.
