Accessing gnatsweb folders selectively within a given database

Folks;

I have someone that wants to restrict access to folders within a given database.  For example, they want person A to have access to a, b, and c folders from gnats-adm, but for person B to have access only to folders a and c from gnats-adm.

Is this possible?  This is on a UNIX system, and my folders within the database are already set at 700 and are owned by gnats, so I can't use chgrp to modify access (and I think it won't make a difference, given that they are tightly held already).

I am assuming at this time that I would have to create /etc/gnatsd.access, create separate databases for a, b, and c, and then use /etc/gnats.conf and /etc/gnatsd.access to limit access to each of these folders.

I'm presently using gnats 3.113 and gnatsweb 2.93.
