Discsubtitle groupings

[simbun]

I guess if they're albums then they'll be returned from an album UPnP search, or would they be akin to Groups like you have now which don't show up in searches?

The reason I ask is because in BubbleUPnP, if I navigate to 'The Beatles' via AlbumArtist, I can click on the 3 vertical dots alongside one of their albums and it gives me the ability to show 'Albums by The Beatles ...', that hopefully would return all the albums outside of box sets plus albums in box sets e.g. 'Sgt Pepper' contained in the box sets 'The Beatles' and 'The Beatles in Mono' as well as the album 'Sgt Pepper (Super Deluxe Edition)'.
