Address sharing needs work! Please make it possible to (1) query on address sharing and (2) update address-sharing via import. Currently, finding what constituent or relationship records an address is shared with can only be manually looked up record-by-record. Unlinking currently shared addresses also must be done manually, address-by-address, and the options are either to unshare all links, or leave them all as is. If it's not possible to update sharing via import, at least it would help to be able to select some-but-not-all records to manually unshare.
Anything (checkbox, or field) that would indicate that an address is shared would be helpful. Knowing that spouse pairs, or org contacts share an address, and being able to query on that would be beneficial
