Sonic myDVD Help

Just a simple question that I couldn’t find an answer to when using search. In Sonic myDVD is there any way to change the graphic/image used in the circle below? I know you can choose frames out of a clip for the button image. But what about a different JPEG. I want to create some advanced sub-menu’s but this program is limiting that.

So anywayn to change the graphic below?
Or will it always be that arrow thing

Anyone? Maybe I posted this in the wrong section?
