Thank you Greg for the speedy solution. I figured it must require a more in depth solution than simply playing around with the group placements. Sometimes I can achieve what I want by creating invisible groups. Didn't help in this case. Thanks for the code example, very helpful. If you ever visit Vancouver Canada I'll buy you a Cappuccino.
