DSGC Fire "Items Created' Fire Event issue

Hi,

I come into a situation where I am dynamically loading a DSGC into the scene. I want to have sounds play when I this is finished loaded.
There is a Fire "Items Created Event" in the DSGC but when I click on on it all option below disappear.

I looked into it and for this function I need Master Audio prefab in the scene. When you have Master Audio Persist across scene and having not Master Audio Prefab in the scene this feature is broken.

I'm using Newest MA and unity 4.6

I have added a screen shot.

Thanks
