export/import metadata of pins which use urlstore

If I understand the urlstore feature correctly than there's no way to export and import the metadata from one node to another one.

Say I want multiple nodes to access the same 10 TB of data via URLs then each of them would need to fetch, chunk, hash etc the full 10 TB.

It would be nice if the chunking, hashes and URLs could be exported on one node and imported on all the other ones :)
