Set icon for library mode?

[xfiring]

While I'm asking questions, is it possible to set a different icon, rather than the default folder, for anything in library mode?

I'd like to change genre folders, year folders, etc? I am not talking about replacing just the image in the media folder of the skin, but assigning it an icon, similar to how you can in file mode.

Thanks
