Confidentiality Footer/Watermark/Header/Card

I propose the addition of an automatic header/footer/watermark feature for all printed cards/dashboards and possibly a footer for all dashboards/cards, especially when being presented. We present a lot of financial data in our dashboards and our legal department would like to put confidentiality statements on sensitive visualizations.

A similar solution would be to allow for a specific card be automatically added to a dashboard when one is created. Similar to a default template. This would allow admins to add a legal statement card to the bottom of all dashboards by default which the users could remove if it did not apply.
