Custom Music on Shards

[Yali]

This is a little request...

Could it be possible to not restrict the sfx files on the shards, meaning that you could technically add custom music by replacing the existing files without them re-downloading when linking to an Age? I've always wanted to use more D'ni themed music in my Uru experience - like Turjan and Robyn's work - rather than the existing music by Tim, some of which I find grating.

Also, I really want to swap out the linking sound effect for either the Exile or Riven one which are a hell of a lot more powerful and sinister sounding.

Would this be possible?
