Change state of drop down menu selection to visited when page has been viewed.

I followed along the great webinar on creating drop down menus for a course I'm building in Storyline, and initially I was going to have the menu item change to visited state when the user clicked on the menu item, visited the page, then returned to the menu. Client now requested alternate navigation within a menu using go forward button from a page. Now I also need the menu item to change to visited when the page is visited, whether or not the menu item was clicked on. Is the only method to create a second variable, and change state to visited with a second OR  condition?
