Using Membership Lite with Wiki: how to restrict wiki access?

Hello,

I am using the full Wiki plugin from WPMU Dev, and just installed the Members Lite plugin to trial it before buying the full version. The website is at http://www.healerswiki.org

Is there a way for me to restrict access to the Wiki articles using the Members Lite plugin? I don't want to have to go through every future Wiki article and add a <more> tag for example... but would instead like to use a Category type of access restriction, like the one available for blog posts.

It would be particularly useful if I could restrict the Wiki access on a sub-Wiki level, so that main pages could be accessible to all, but deeper content articles would be subscription-only.

Are these two plugins compatible with each other to restrict access in that way?
Thank you for any input!

Marcus.
