Can we save image slices in sub folders in Photoshop?

Question

I am using Photoshop CS5, by default, Photoshop saves image slices in a folder named images.

This is fine but there are lots of images, saving them all in a single folder becomes quite messy.

What I would like to do in Photoshop is, it allows me to specify which sub-folder a slice should go under the default images folder.

For example, a website template PSD file, I would like to save image slices that appear in the header under images\header\. Maybe for the images in the footer, they should go images\footer\.

Of course, I can group them manually after the slices are extracted.

If possible, I would like to define them in Photoshop, so that every time the image slices are extracted, they each go to the specified sub-folder automatically.

Is this possible in Photoshop?
