How do I change a menu button color when a section is complete

I have created a selection screen (menu) that lets participants pick how they want to move through a module: menu item 1, menu item 2, menu item 3, and menu item 4. Is there a way to change the color of a menu item or add a check mark next to a menu item when you have completed a section so a user can check their progress in the menu and know what they have already done. An explanation of how to do so would be very much appreciated. Thanks! (I am using Captivate 7)
