Improve file naming convention of captured emails saved as PDFs

Saving emails as PDFs from the Emails BI Report results in file names that are not clearly indicative of the email that was exported. Screenshot examples attached.

If many emails are saved as PDFs, in the destination folder (e.g. Downloads), sorting the list of exported PDFs file names should be sortable chronologically (by actual mail date in file name) and logically (some indication of original sender) without any file name editing needed.
