Creating a new content item using AA

Using rhythmyx 5.7

Is there an easy way to create a “NEW” content item using the Active Assembly interface.

I know its possible to edit existing items, but when i create I only get the standard content editor.

The reason I ask is using AA seems a good way to be able to customise a page template for my standard users (whom we try to avoid giving anything complicated to), and only showing them the fields they need to complete.
while keeping the much more complex and full set of fields for expert users/admins
