Categories/Tags for Sound selectors

[sunmachine]

Unless I'm missing something you can't categorize the sound selector items.
It would be great to be able to define multiple tags for a sound. Common tags like Piano, Strings and so on should already be available by default.
A controller could then use these tags as filters that can be set by the user to quickly find the sounds he's looking for.

For MIDI sound modules that have multiple banks we also need some kind of bank selection. Or is this already possible?
