Is there a utility to push data from the files attached as references into a document into the document.

I would like to attach a number of files as references to a transmittal or ECO document and have some of the variables (number, description, rev and version level) be populated into the document itself without having to type them in manually. If I could even get that information into the data card it would work, because I can push information from the data card into the document itself.
