Is there any common research model for supersonic transport? Is there any common research platform, like the Common Research Model of NASA for supersonic transport flight?

I assume that in aerospace industry, every company has his own research platforms depending on previous projects but was there any common model that companies shared for this purpose?
According to NASA here:


  This test case is an aircraft concept previously used as an optional
  case (LM1021) in the 1st Sonic Boom Prediction Workshop. This
  configuration is described in the following reference: John
  Morgenstern, Nicole Norstrud, Jack Sokhey, Steve Martins, and Juan J.
  Alonso, “Advanced Concept Studies for Supersonic Commercial Transports
  Entering Service in the 2018 to 2020 Period,” NASA
  CR-2013-217820,DOI:2060/20130010174. See NTRS Record. There is also a
  description in the following reference: John M. Morgenstern, Michael
  Buonanno, and Frank Marconi, “Full Configuration Low Boom Model and
  Grids for 2014 Sonic Boom Prediction Workshop,” AIAA-2013-647.
