Is there a way to include sub-menus into Easy Blogging

It seems like a number of others have asked this before. From early last year as well. I'm still reading through the discussions I've found so far for a way to get this done. I'm not against diving into the code myself, but I'm hoping someone out there has already achieved this.

This response didn't do what I needed it to do.

I have plugins which have a dashboard & many sub-menus of their own (e.g. Membership Premium & eNewsletter). I want to use Easy Blogging to add a link to the navigation for a given plugin's dashboard and will include all the sub-menu items.

Any functionality similar to this would be okay for as long as I can define a menu item and sub-menu items in a fashion similar to the native WordPress Menu management system.

Thanks.
