Looking for way to change ring/message alerts on schedule

[sykosoft]

I need to be able to schedule different sounds to be used for my ringtone/text message alert sounds on a schedule. For instance, during the day, any text message sound is fine, I'll notice it, but at night, I'd like to have it automatically switch to a louder custom wav to wake me up when I receive a text message.

If anyone knows of any way to do this, it would be appreciated.

Thanks,
Michael
