I found the answer to the second question. The profiles are displayed in the order that they were created. If a profile is created and added to an existing group, the it is displayed in sequence after the existing group or subtask profiles.
Best to have a plan on paper first on how you want the group to be put together, then create the sub tasks first and then the group profile last.
