no, this is not something we have implemented. Yet, this is quite simple in principle to generate the highest 
order in the geometry and to post-process the mesh and reduce locally the order of the mesh

You can use a python script that would look like

g = GModel ()

g.load('yourmesh.msh')

face = g.getFaceByTag(1000)

print face.getNumMeshElements()
