Half Coupling as a Nozzle on an equipment piece.

It is pretty common practice on plant equipment pieces for them to have threaded (or even socket welded connections) defined as nozzles.  Is it possible to use Nozzle Manager to define these types of connections on the equipment we model in OpenPlant?  If this cannot be done with Nozzle Manager what would be the best practice to add these types of nozzles to equipment?  Thank you in advance for your response...
