It would be create if a “connect-boards” column (and any mirrored columns) could be included when there’s an automation for a change in one board to create an item in another board.
For instance, we have 1 board that lists all of our contacts. Those contacts are linked to board X where, when confirmed, an automation triggers an item to be created on board Y. Both board X and Y have columns to connect to the contacts board, but the contact linked in board X cannot auto-populate onto board Y like other information (item name, statuses, etc.).
