Membership Plugin: How do I create rules that apply to blog owners?

I need to be able to create global rules that include all users, including network blog owners. Currently this does not seem to be possible as the owner of blog id 2 does not show up in the list of subscribers under blog id 1. I tried enabling the global tables option, but that did not seem to do the trick.

Please LMK if this is possible, and if so how to go about configuring it.
