When I have 5+ levels of hierarchy in the tabbing, the tabbing doesn't seem to suffice to show organization and I cannot understand the hierarchy from just viewing the tabs I have tried using highlights but I have too many sections and subsections to have distinct highlight colors.
My solution is to make brackets on the left, to the left or right of the "at risk" column, that open at the summary and close at the end of the contents associated with the summary as shown in the attached image.
