Perhaps I am misunderstanding you, but that sounds like a like more
work than I want to invest. I was looking for an automated system.
I have investigated using SQL with LaTeX to get what I want. It won't
be easy; however, it seems like once I get it up and running, it will
take care of itself. (famous last words)
