[Zope] CMF Filesystem Directory View

[Poor Yorick]

Hello, if the answer to my question is already available somewhere, please let me know... I looked around quite a bit.  I am trying to add a filesystem directory view (Zope 2.7, Plone 2.0), and can't figure out how to add new directories to the list of directories available to choose from.  Could anyone clue me in?
