better Multiple Artist/Genre support in LUMIN controller app

[psme]

I'm thinking, before MinimServer adds support for multiple <upnp:artist> tags, can there is be any temporary workaround using TagUpdate file.

Does TagUpdate support partial match and replace? For example:

artist in metadata:

FirstName, LastName

in TagUpdate, set a rule to replace ", " to ", "

@ARTIST=,
=ARTIST=,

So that, LUMIN app won't auto separate the artist name, and visually it won't look so bad with a extra space!
