OSX Notification Center, change alert sounds?

[Solomani]

Anyone know of a way to change the default sounds for the Notification Center alerts? I don't see it. I go to System Prefs --> Notifications --> Calendar

The only option is to either enable/disable the Play Sound When Receiving Notifications

But the options don't allow me to change the alert sounds. Anyone have any ideas? Third party solution?

Follow-up:

I found that you CAN change the Alert sounds, but you have to go into Calendar first and click on the individual event. From there you can change how the event alerts you, including the alert sounds.

However, this is still not ideal. I would love to be able to change default Alert sounds for ALL types of Notification Center events and things.

I don't understand this. Why can't I change each app's notification sound individually?
