Is there a way to search or run a report for constituents who have the same addresses as each other? For example, a couple or a household with two or more members living at the same address are not registered in Altru with those primary relationships. I know the full/incremental duplicate constituent report/process finds constituents with similar names and addresses, but nowadays many people keep their own last name while living with a partner, so Altru doesn't pick up on this.
This would help immensely when I only want to send one letter per household for appeal mailings.
