Surface Definition out of 3D Faces, using the same triangles

[a_comenale5CSSL]

Hello, I have a survey made of 3D Faces. Now I succeeded in creating a Surface Definition out of it, but Civil3D will recreate the triangulation, therefore creating a different and probably less precise approximation than the one I had (see image below, survey is in brown and new triangulation in grey).

Would it be possible to use the same triangles as in the 3D Faces survey?
