Levels of protection

Is it possible, using this plug-in, to have a few ‘levels’ of security. For example, on a club web site, there is the public section. Then one needs a ‘members-only’ section, and within that members-only, as a subset, should be the ‘club-executive’ section, which are those pages for the elected executive. The executive members can see all members-only pages, but members who are not elected to the club executive cannot see the club-executive pages.
