Menu bar / I want to link to a page outside of wordpress

I’m using the ‘Pressplay’ theme. This theme comes with a horizontal nav bar that is created from adding pages in WordPress. I would like to add a ‘Home’ page link to this bar, but this page doesn’t exist inside of wordpress. The rest of the links in the nav bar are fine. I just want one of them to not go to a wordpress page. Is there a way to do this?

Thanks!
