It would be very helpful to support automations triggered by mirror columns that are connected to multiple boards. Currently, this functionality is only available when a mirror column is linked to a single board, which limits more complex workflows.
My use case involves 5 teams sharing the same form, with all responses collecting on a main board for record keeping. Each team manages and updates the status of their assigned responses on their own team-specific board, and that status is mirrored and synced back to the main board successfully. The missing piece is being able to trigger an automation on the main board based on that mirrored status. Like moving an item to a new group when the mirrored status is marked as 'Done.' However this is not possible when the mirror column is connected to multiple boards. Expanding automation support to include multi-board mirror columns would allow this workflow to run automatically from end to end.
