Unfortunately, there is no way that I'm aware of to accomplish this using pipe networks. As you can see, structures are not one of the things you can project onto a section view.
You could create blocks on your structures that you then project but they won't change as your structures change.
Sorry I don't have a better solution for you.
Perhaps this is a useful feature that Autodesk could include in version 2024, after they've implemented the holographic-cloud-based-silt-monitoring toolset that we are all clamouring for.
