You can place cells in a cross section when displaying breakline features as 'crossing features' in a section. You would need to have these surface breakline features generated and it can display a cell or symbol at the locations where the feature(s) cross the sections.
Another option is to just use the place cell command in MicroStation (CAD platform portion of PowerCivil) but it would not have any civil intelligence and would not be tied to the cross section set, merely a graphic created but it can be rotated and scaled just using the MicroStation/CAD tools.
