That should do it. It worked for me without problems - though I have only 2 drm pdf's so it may have been a fluke
For regular non-drm pdf's you can just dump them in the Library with add files - though it's useful to check/modify the meta-data using a pdf program that allows you that since the Library takes whatever it's there as author/title and so on and you cannot change it directly.
