Moving lots of playlists to an iPod at once?

Howdy.

I just had to reset my iPod because it was corrupted. I now want to move my playlists back to it, but there are tons of them, in various folders. Is there a way to move an entire folder of playlists to an iPod, without having to drag over every one? Right now it seems like I can make a folder in the iPod, and drag playlists one at a time to the iPod, and from there into the subfolder--but I can't just drag the whole folder over. This way it's going to take a long time to do them all. Anyone know a faster way? I'm currently using the manual mode because I have too much music to just sync the whole library over.

Thanks.
