Add a unique identifier to the PDF File names when downloaded by TaxPayer

It would be great if the PDF file names have some kind of unique identifier, like the name on the return, to identify them. I have a client who is receiving multiple returns and can differentiate the links by the name in the email, but when the files are downloaded they are all generically titled e-file forms, which makes it difficult to determine which E-File form package is for which company.

A way to control this in settings would be nice as well.
