I think it would be possible to add something like this. I will investigate and post back here.

Collapsing and uncollapsing would be need to be implemented by the control point as this controls the user interface. The UPnP protocol limits the server to sending containers with predefined contents.

I have considered the possibility of adding something like an "album set". In the containment hierarchy, this would be a level above album, so the hierarchy would be

album set (optional)
---album
------disc (optional)
---------group (optional)
------------track

The album level would be for an album with a small number of discs (perhaps up to 3 or 4). An album set would be for anthologies that contain perhaps 50 to 100 discs. An album set would be shown as a collapsed list of albums. The user could click on one of these albums to reveal the contents. These contents would be sent to the control point as a new container, so all the other albums in the album set would not be shown.

When browsing the library, album sets would be shown alongside other albums, so the user would only see the top-level album set until they click on it to see what it contains.

Does this sound like a good solution for your requirements?
