I sort of agree with you Ann about templates. They can lead to a 'standard' approach rather than one which best suits the track. But then again, isn't creating sub-groups a mechanical task best left to a computer so we can spend our time doing the 'artistic' stuff. Even if you used a template with one sub-group set up you could then duplicate that track which would be faster than creating it? Or a template with a wide variety of groups setup could help - you just select and delete all the sub-groups that aren't appropriate for the track.
