Global Header & Footer Across Multisites

Hi. I'm setting up a site for our local High School. Each faculty in the school is going to have their own multisite sub-site so that staff within that faculty can only update their own content, while giving them flexibility to change their sub-site menus, etc.
However, we'd need the header from the main website (with the main menu) and the footer to be global across all the sub-sites, with no access to change them by faculty staff.
Is there are WPMUDEV facility that will let us do this?
Thanks in advance.
