Enfold Theme, How can I export a header menu from one site to another?

Hello, I have a multisite configuration (Enfold Theme) that I am building for the American States Assemblies and am creating a site for each state, or 50 sites in all. They will be using the same links in their header menus for each site. Each menu will have 50 plus links in the menu.

Is there a way to export a completed (50 state) menu into the other 49 sites so that I do not have to create each one manually?

Thank you for your help!
