How can I display multiple GENRE tags?

I'm converting my music collection to FLAC format. It seems that FLAC can support multiple GENRE tags and I prefer this method over the alternative which would be to have a GENRE tag made up of various elements (Indie;Britpop;Rock etc).

MP3Tag can create as many GENRE tags as I need, but I can't figure out a way to make it show me more than one GENRE tag at a time. Is it possible to display various GENRE tags which have different content?

Cheers!

I can see multiple tag fields in the tag panel and in extended tags.
Where do you want to display them?
In the file list view, you can change the value of the genre column to $meta_sep(genre,\\)
