question feedback style

HI

I an using random question slides pulling questions form a bank and want to change the default correct and incorrect feedback. I know I set the message in the quiz preferences, but how do I set the position of the feedback boxes? I want the feedback to appear unmder the question - not on the right hand side of the screen. I can go into the question pool and set it for every question but I have 100 and guess there must be a way of setting this somewhere?

Thanks

A
