automatic resource loading(?)

Hello all.

I have Jigsaw 2.2.0 installed on Win2000.

I have configured the root directory of Jigsaw at C:\www
The stucture of this directory changes very often.
Is there some way to tell Jigsaw to automatically load resources from
this location, instead of having to delete old 
org.w3c.jigsaw.resources.DirectoryResource(s)
and add the new ones all the time?

Many thanks.
