Can't be done. Not part of pdf, unless one goes to quite some troubles
defining all annotations as widgets while using the default button
things. Far from ideal. Just generate a nice A4 version as parallel
document.

It completely depends on what you want to do. When you mix text and
figures in the way I think you do, I would not use backgrounds, because
that way you have no way of telling where the text should start. Just
use something like:

\externalfigure[name][factor=max,height=.6\textheight]

which gives you name scaled to the max, unless the height
>.6\textheight
