How do I change vibrate settings on Android

Question

Hi guys, wonder if any of you can help?

I am trying to find out how to change the default vibrate pattern for incoming calls, SMS etc. I know how to create my own custom vibration and have it vibrate onClick() or in my own notifications but do not know where to override the system wide settings. I thought AudioManager.setVibrateSetting would have been it, but that only allows on, off or silent only.

Is there any system wide setting I can change so that I can use my own vibration pattern?

Thanks.
