Isn’t the back to top button meant for this? I hope I am understanding your query right – looks like you just want the option to let users to navigate to the top of the page after scrolling to various sections.
If you really need this, it is possible to achieve this by discarding auto-built menu and creating a regular WordPress menu manually with all the links to various page sections and a Home navigation menu item which has URL like – http://yourdomain.com/#container instead of the default – http://yourdomain.com/ as URL. This will make the Home link to jump to the top and will also help user to move back to home page when other pages like Blog are open.
