The initial description might be misleading. What I tried to do is repeatedly set manifolds for circles on X-Y plane. Now I use STL container to contain different pointers of SphericalManifold instance and correspondingly assign distinct manifold ids, it worked out. But it might be a non-smart way. See the attachment for a small demo of the geometry I created based on the idea.
