Spotlight Find File; customize search bar?


Hello all!

When I do a spotlight search from the desktop, the old cmd-F in Tiger. It gives you the options:

Servers | Computer | Home | Others...

If you want a specific server volume on your network, you have to hit "Others..." and specify the volume via the pop-up menu.

Is there a way to include specific volumes in the options bar every time you cmd-F, without going through the pop-up menu?

Right now my workaround is to use smart folders for each server volume with some dummy text in the search field(s). It works but it would be nice to simply have the volumes I want as search options in the first place.

Any help would be certainly appreciated.
