Bridge CS4 - Image processing into subfolders

Design Premium CS4

Bridge 3.0.0.464

XP Pro SP3

Problem: Image processing into subfolders

I have a folder with several subfolders containing JPG files.

I want to reduce the file size by reducing the quality.

I use the following to do this:

Tools | Photoshop | Image Processor

Bridge doesn't appear to have the smarts to traverse down into the subfolders i.e. one has to do each folder individually.

Is there a way to have Bridge image process down into the subfolders? Thanks in advance.
