One edit alters many?
 

I using OmniGraffle Pro. I'm trying to make organiser pages for my filofax (too cheap to buy the inkjet stationery!)
This is what I am trying to achieve:
I have a sheet set up with the outline of 3 pages for the filofax on it. I want to be able to amend one sheet (eg add ruled lines, check boxes, and a title) and for this cheange to be reflected on the other sheets. I thought this might have been possible in the Master Canvas section, but I am clueless as to how to go about it.
Any suggestions?
