'display pages' = 'at top level'
'sub pages to display' = 'display all'
'sup-page levels' = 'display all'
and then use css (and/or js) to handle display of the sub lists to create dynamic menu. Might not be the method you invisioned, but it'd work. :)
If you were going to make a template, it's the same on every block. Just copy the blocks view to:
blocks/autonav/templates/accordianTemplate.php
...and then make the changes you need. Best of luck.
