Albumartist as performer tag

[ebbot]

Hello!
I recently updated my Netgear Pro4 NAS to minimserver2. While at it, I got an idea. Using the album artist tag for something useful. In my collection, I only use the artist tag, except for compilations where I use Various as a tag for album artist. Elsewhere album artist is blank.

I want to use the album artist tag to show the performers in my jazz albums.
I saw this on the forum: To add performer information to album artist names, add this to tagFormat:

AlbumArtist.displayFormat={$albumartist^$performer^; }

Now that sounded promising! But nothing showed so I added
aliasTags = AlbumArtist:Performer

That worked fine, BUT when browsing Artist it now show All Artists, even the artists from compilations! Artist and All Artists are the same.

How can I resolve this issue? I use mconnect on an iPad btw.

I can not post my config as I get an error...
