Automatically add new items to connect boards column


I would like to be able to set an automation for the connect boards column in a high-level board to automatically add items that get added to the linked low-level board/s.

Or upon setup, that there be an option to select ‘all items’ and ‘all items within group’.

Currently, I have to manually add any new items that are made in the low-level board.

Hope that makes sense.

Thank you
