I want to have a board with a master list of customers as the first column.
On other boards I want to be able to use this same list (and if the original changes I want the connect boards to change). One board might have service info, another maybe sales, a third might have files etc…
It appears you cannot mirror the first column. Is there another workflow people use. Maybe the first column is just a sequential # and then use a second column as “customer name”. Then connect a board and mirror that column?
How do people reuse this information in the first (index?) column?
