dimension changes to multiple floors

[joeybuilder]

I swear, I promise I looked for this answer, but Help is like an endless forest where you can't find the tree you're looking for.

I have in hand a foundation plan and 1st and 2nd floor framing over it; no roof structure yet. I realized I need to make a 1st floor addition a foot longer; the foundation and 2nd floor must of course match it, snap to it if you will. Is there a simple way to apply a change on one level to all others or must I change each level one at a time?
