Grouping Mood Tag contents

[claas]

Hi,

I started using Songkong to add the "Mood" tag to my files.
I hope to achieve something similar to what iTunes is doing with its "genius Playlists" feature, just not dynamically but by navigating through MinimServer-generated menu items.
I'm now wondering if it was possible with MinimServer to group contents of this/any tag.
e.g. I do not want to distinguish between "Calm" and "Very calm" but want them being displayed as "Calm" (or any other user defined value).
So similar to what is possible with tags but now with values of a tag.

If not necessary I do not want to change the values in the files as then with the next run of Songkong they might get overwritten again.

Thanks

Claas
