Preview from dropbox without downloading a .psd

Since Apple finder is always broken and stops giving previews on psd files after a while, I thought I could use Bridge to preview my files on dropbox.

The point is, I don't want to locally sync everything, but have a preview from the cloud then download just what I need. Every time I select a psd file on Bridge, however, the file is actually downloaded in background, then the preview is made.

Is there any way I can make this work?
