storing a group as a customProperty

[Peter Brigham MD]

Is there a way to store a background group of buttons as a  
customProperty of a stack? I am trying to cover the possibility (in a  
utility) that a user in the IDE might do a "select all" and delete all  
controls on a card, and I want to ensure that I can easily place the  
deleted buttons back on the card again as a background group. If  
there's a way to store the group as a customProp that would be the  
easiest way of preserving it -- then I could just retrieve the group  
and place it again.
