Multiple TPE2 Tags

[aposchma]

Hi, i am using minimserver 2.2 update 246.
i would like to use multiple Albumartist tags in my library. I can easily tag my music with multiple TPE2 Tags, but none of these Tags show up in the renderer.
They only show up if i use only one single TPE2 tag.
Example:
TPE2=Hans Jürgen Stockerl, Nils Nelleßen, Judith Mauthe
shows up in the renderer, i can search for any part of the name and the tag is found

When tagging with multiple Tags
TPE2=Hans Jürgen Stockerl TPE2=Nils Nelleßen TPE2=Judith Mauthe
none of them shows up, all three TPE2 Tags seem to be completely ignored.
I can find none, search shows no result.

Is it possible to make TPE2 tags behave the same way as TPE1 or TCON tags. These can have multiple values.
