display easy blogging menu item for several roles.

Easy blogging has a nice option to enter menu items by capability or role. I need a slight variation on this. I want to show a menu item to several roles that are lower than the admin role. Easy blogging has the option to display the item for one role only, eg subscriber only, how do I get an item to show for subscriber and author when I want to exclude admin?

I tried creating a new capability with capsman or role editor plugin but they both assign the capability to the sub site admins.
