Sociable position in post

Hi, I’m using Sociable on my blog, and I would like to know if there is a possibility of selecting the configuration of the plugin an option for social networking links to only show up at the top of post and not top and bottom or just bottom (I think this is the default option). I look forward to your reply. Thank you!
