Is it possible to copy slices to another PSD

I inadvertently cleared the slices and need to get them back (file had been saved and session closed). I have another PSD file that has the slices layout I need but not the correct layers. I suppose I could just copy all the layers over but was wondering if there is a tool that allows you to save and restore the slices layout?
Thanks!

As far as I know you can't copy slices. I think your best bet is to drag layers over from the other document and delete the originals. You can even elimininte all the layer data and use the sliced document as a template.
