[Gmsh] physical groups from CAD import

I am wondering whether it is possible to define physical groups in a CAD 
geometry (especially using OpenCascade) which will be recognized by Gmsh in the 
meshing process.

I have created a simple geometry using Salome, named the primitive bodies and 
their boundary faces, and imported it as BRep file into gmsh. However, the 
resulting mesh contains no physicals.

Is it possible to define physical groups using CAD tools in the BRep file, or do 
I have to define them manually in Gmsh? What are the required steps?
