Is it possible to assign different menus (distinct menu modules) to the main nav area for use with the megamenu? For example, on the Home page the main menu module appears as a megamenu, and on the Blog page a menu module for a menu named "blogmenu" is used for the megamenu in the mainnav position

The megamenu interface lets you select and save layouts for multiple menus, so I assumed it was possible to have it control different megamenus on different pages, but I cannot get this to work. Even if I assign separate template styles to pages where I have assigned a different menu module to the mainnav position, if I am using megamenu I can only get the mainmenu module to appear. I have to turn megamenu off and use a regular Joomla menu module if I want to use a different menu on some pages.
