Does anyone know if rtorrent supports selective files?

I've tried setting priority to off but does that make the file not download?

I really love rtorrent (just got used to using it) and I would like to continue to use it but i do need selective downloading as a feature (i might have to go back to transmission ugh GUI applications)

btw selective downloading (in case it's unclear) is downloading specified files on a torrent instead of downloading the entire thing

i'm guessing it's a really simple solution and i'm still too much of a noob in ubuntu
