Importing survey spots with tags

I'm trying to bring survey data into InRoads running in MicroStation.  The data is stored in an AutoCAD file as Shared Cells with tags.  All the shared cells are placed at an elevation of zero.  Is there a way I can import this data to a surface with InRoads reading the tags for the elevations rather than the element elevation?

Thanks in advance, all...
