How to prevent user from posting event to group?

WP 3.5.1, BP 1.6.4, Membership 3.4.4 beta 1, Events+ 1.5.4-BETA-2

I basically have two user roles for my site that I'm dealing with: Club Owners (similar to Editor) and Club Members (similar to Contributor).

I would like to set up the events plugin so that only the Club Owner can post club events. I've been trying various settings under Events Capabilities but find that the Club Member can still go to their profile under Events > Add Event and create an event for a group they belong to. Is there a way to prevent this?

Better yet, is there a way to completely hide the Events > Add Event tab from their profile pages?

Thanks,
Jeff
