Short answer- no.
Long answer: The unity terrain editor does not store information as a mesh the way Maya does. Unity terrains are a height map and a texture map, which is why you can’t create overhangs, and also why textures on cliffs don’t look all that good. It is possible to import raw data into the terrain editor, but the format is not exactly useful for mesh editing. On the other hand, a nice way of using the terrain editor is to use it only for large-scale geology, and for any interesting details just use normal meshes anyway!
