Multi-pins how to use cylindrical-Mesh

Hi guys,
I know that openmc-0.13.0 has allowed us to use the cylindrical mesh for our model.
And now I want to set the mesh on each pin of my model , but I dont know how to locate the origin of the mesh for each pin.
I have read the source code of the mesh in user documentation , and did not find the information I want.
Does cylindrical mesh allow us to use on each pin?

Best regard!
