Yep.

The '+' is an implementation of IAdding.  You first need to register  
the page for the interface, a la


   <browser:page class="path.to.your.view.class" name="addWhatever.html"
            permission="zope.Public"
            for="zope.app.container.interfaces.IAdding" />

and then register a menu item for the adding that points to it, a la

   <browser:addMenuItem
       title="Whatever"
       factory="path.to.your.whatever.factory"
       permission="zope.Public"
       view="addWhatever.html"
       />

The factory is used to get the interface to check constraints.  You  
might be able to do without it; check APIdoc if you are curious.
