change mulptile fields across several doc's

Is there a way to change fields across several different documents? We have
roughly 148 different document templates. Is there a way to set up fields in
these so that we can run a batch or something simmilar to change the headers
and footers on these files to match the project they will be applied to.

Probably a total of 2 -7 fields per document.
Project Name
Project ID
Contract #
and a couple more

Having to go through these all by hand to set up new projects takes to much
time...

thanks
