Presentation of multi-artist data in All Artists view

[ac16161]

I currently have the Artist tag for multi-artist tracks set to something like this:

Artist "B.B. King; Van Morrison"

When browsing by All Artists, I would like the same track/album to appear under B.B. King and separately for Van Morrison. What I have is an All Artist entry for "B.B. King/Van Morrison". With many multi-artist tracks where the contributing artists are also main artists on other albums, this is creating a huge amount of clutter in my All Artists view. Is there an option I can set to force each contributing artist to be treated separately in the All Artists view?

Thanks.
