Permissions question - grant guest access to all subalbums, but not to the root Gallery?

Hey gang,

This ought to be easy, but I'm banging m'head on it.

Make the root album (named Gallery) only Admin access (no guest access).

Each subalbum, as it is created by Remote, will be owned by Admin, and automatically have the hidden flag set, and automatically get permissions of guest view all versions.

Clearly, after a subalbum is created, I can log in and set the permissions on each album after it's created. Is there an automatic way to get set these sub-album permissions (hidden & guest view all versions), without giving guest access to the root (Gallery) album?

Many thanks!
