Batch move files into separate subfolders

Here's what I'm doing:

I pull up a folder of images with separate subfolders.

I check "Show Items From Subfolders" in the View menu.

In the Filter panel, I check "portrait" in the Orientation category.

Now I have all these portrait-oriented images from several different folders.  Now I'd like Bridge to create a "portrait" subfolder in each folder, then move the portrait-oriented images into their corresponding "portrait" subfolders.

So....  is that possible?  Little help?
