Box set tagging

[lg.lindstrom]

Hi

I've invested in a cd box set, "Bach Cantatas"
( http://www.monteverdi.co.uk/shop/albums/...mplete-set )

It consists of 28 volumes, and every volumes contains 2 CD discs.

How should I organize/tag this kind box set ???
I don't want to see all discs when browsing albums.. just the "Bach Cantatas" entry.

I wish that I could tag this in such way that,,
Top level => I can see the box set ("Bach Cantatas")
Selecting the box set => I can see all volumes (vol01, vol02, ....)
Selecting one volume => I can see two discs (disc1, disc2)

This is a valid problem for a lot of box set's.. that contains albums that are double disc albums.

I am using BubbleUpnp as control point
