Data linking?
 

I have been using OmniGraffle to track and diagram some data. There are some numeric data that stay constant across several diagrams, however their values change occasionally. Is there a way to link them so that changing a value on one diagram, will update it on another? How about linking all to a database so I don't even have to edit them at all in Graffle?

Feel free to whack me if this is a dumb question that I've missed the answer to in an obvious location.
