Different menu on the homepage for Werkstatt theme

I am using the Werkstatt theme on the website scentfolioworks.com
I need to have a different menu displayed on the home page. For the internal pages, the regular navigation menu or the mobile menu will be displayed. But since the Werkstatt theme provides only 2 menus, I am not sure how to implement this. Please help.
