I'm wondering if there is a way to add a level to Texinfo's hierarchy, so that there is a level below subsubsection. I'm including files using @include, @lowersections and @raisesections, and occasionally I "bottom out" and end up with a partially flattened hierarchy where there should be a fifth level. The content is very hierarchical in nature, so retaining this structure is very desirable!
Thanks! - Benjamin Kalish
