Limit "More" tag restriction to specific categories

My site is open for all except one parent category "Training" and its children. I would like to have "Training" visible, but restricted to members only after the more tag. I can't figure out how to do this without the "more" restrictions being site wide. I want users to be able to read my blog posts, see the teaser content for the Training category, but only see the full Training content if they are members.

Can I limit the "more" tag rules to one category?

I'm using the beta version of the plugin on WP 3.2.

Thanks!
Jack
