How to show 3D lines/objects in OpenRoads Profile?

How can you view 3D elements in the profile view for OpenRoads?

What I'm trying to accomplish is when we create our profiles, we need to know where cross drainage features are and their size/height, etc. etc. With the Geopak Classic method, this isn't an issue because you draw the culverts into the design model normally and draw your profile around this. However, with the dynamic nature of OpenRoads this isn't as clear cut. If I draw a 3D box for a culvert, the culvert is shown in the cross section view as expected (and hoped), however, it isn't displayed in the profile. How can we reference information into the profile for designing the profiles?
