Can MinimServer make Naim 272 display Composer tag?

[haggis999]

I am checking out a Naim NAC-N 272 network player and have noticed that it suffers from a common problem that afflicts most players. The Naim's own display and the Playing Now page of the Naim app are optimised for pop/rock rather than classical music.

The default display seems to be the Artist, Album and Track tags. The Composer tag is nowhere to be seen (though it is present on all my FLAC files). Is there a clever trick with MinimServer's TagCustom setting that can fool the DLNA renderer into using the Composer tag in place of the Artist tag?
