[Gmsh] labels from brep or step files?

[j s]

I'm experimenting with FreeCAD to generate a mesh with multiple 
materials with the brep (or step) format.  Unfortunately it doesn't seem 
possible to label the surfaces or volumes so gmsh considers them as 
physical names.  As far as I was able to research, this is named 
Topological Naming, and it is currently not available in FreeCAD.

Are there any open source solid modeling tools which support this? Does 
gmsh support reading in the names from brep or step files (or any other 
format)?

Thanks,
