Suggestion - the mirrored board will be able to be connected only to a specific group in the connected board

After connecting a board to an item in a “high level board” - we add mirroring columns.
It will be very efficient if I would be able to choose if the mirrored column will take data from all the board or only from a specific group in the board.
Once choosing a whole board or a specific group, every new item will be added automatically to the connection.

THIS ^^ is a massive benefit to organizations that need to roll-up based on status/grouping. We have been discussing this need and have been looking at alternative solutions to do this given Monday’s limitations.
