You can try using Brandnav and either Nav Classic or NavBar.
If you go to Dashboard > Appearance > Menus, look at Theme Locations (a box on the left). Select the main menu for Primary, then your second menu for the BrandNav. You can always reverse that if desired.
This will allow you to have two different menus on the same header, without the individual settings of Secondary Nav.Go to the full post
