Restrict the roster to a particular user only?

In Wildfire we can share roster between group/s.

Is there a way to restrict the roster to a particular user?

Why? So that I can create a Group will ALL the users, and allow it to be viewed (the roster) by a single (or couple of) users (Administrative User), rather than by the whole Group.

But, still have sub groups where the roster for that group can be shared with that group/s, etc.

p.s. We are using LDAP Groups.

Thanks!

no way yet, but could be a part of JM-349
