I am currently working in an office where there are lots of letters that all
require the same letterhead. The problem is, people have left and phone
numbers change etc and I am now in the position where I have to go into 20+
letters and edit them one by one.

Is there any way to pull one letterhead into multiple word files? This way I
can edit that one, and have the changes reflected in all of the various
letters.
