Automatic Filenames

I am in charge of redesigning all of our companies current forms. The aim is to have them all with a standard look and try to integrate some of the forms in with each other.

I would like to know if it is possible to have office programs automatically create a filename for a document. For example, if somebody wants to create a letter, they click on the letter template and then that document would be given an automatic file name.

If this can’t be done, how do other places manage the naming of documents and ensure they are consistent through all departments company wide.

Thanks for any help.
