Often your electronic submittal is delivered on a CD or DVD.  The jewel case label specifications often include the

Project Number File Name, Company Name, Contact Name, Phone Number

This information is the same used in fields in the title blocks of your sheet set. Add a 4″x4″ (jewel case inset size) layout to your sheet set and it can be configured to show the required info for your CD label. Get a little more creative and you could design an 8″x8″ foldable inset for the jewel case and include a project description, info about your company (market yourself whenever you have the opportunity), or other metadata for the project.
