Manually manage music but auto-sync one playlist?

Ok so basically, I'm trying to figure out if there is a way to manually manage my itunes library but automatcially sync one of my playlists. The reason being is that I have on artists that constantly changes (assorted singles) which is just a collection of different artists' singles. It would be nice to have itunes automatically sync that one playlist but allow me to maintain control of the rest of the library.

Otherwise, my only way to get around this is to create a folder that contains playlists for all the albums/artists I want to sync and have itunes autmotically sync everything that folder?????
