Access Control: Album viewable to all, but Content of the album not- HOWTO?

hello everybody,

Does Gallery3 support this kind of access control? It seems that its impossible with g2.

I have some albums in my gallery, I dont want that guests can see the contents of these albums.

let me show:

ROOTLEVEL
-> Album1
-> Album2
---> Album21
---> Album22
---> Album23
---> Album24
---> (a lot of...)
---> Album2N
-> AlbumN

I want that the content of all bold albums are not for guests viewable. they should get a login prompt.

But, when guests are in Album2, they should see the album-thumbs of all bold albums.

I tryd a lot of, but I was not able to reach this with the rights control.

Best Regards
