Is there a way to have role based wiki's?

I haven't played w/ the crm plugin, so apologize ahead of time if there is already a way to assign an organization or user to a specific set of wiki's which isn't viewable to all users.

Still want the ability to have certain wiki's available to everyone. An easy work around is to put these notes into assigned issues and create a role where user can only see their assigned issue, but that isn't a very clean or flexible.
