Converting terrain mesh to Terrain Type Object


Is there any way/plugin to convert normal 3D model, terrain to Terrain type in Scene Composer?

I mean, i’m generating terrain in World Machine - export it to .obj - and texture in blender. Now I want place completed terrain to JME3 but it would be great to set that object as Terrain Type (terrain icon) because my game is using special LOD for terrain types (9-leveled LOD with different ranges betwen levels).
