[Plugin: Facebook Page Publish] Publish Custom Posts to Facebook

Thank you for an excellent plugin. Can you provide a hack for me to also publish custom posts to Facebook? I am using the All In One Event Calendar, which creates post type ‘ai1ec_event’

How can I add this to also Publish to Facebook? (The checkbox to publish shows up, but it doesn’t do anything)
