When dragging mutiple elements into a group (Nested Elements Relationship) it defaults to composition, if I want another relationship I have to do it one by one.
Is it possible to hold a key and drag to get prompted for the selection..
If you hold the Ctrl key down when selecting the relationship in the combo box it will change all of the relationships in each combo box in the dialog. Remember to click outside of the combo box for the selection to "stick".
