Allow view to Connect board column and Mirror column on board who are not members of the connected board


We have implemented in our company recently.

How can we allow members in a board to view, connect board columns and mirror columns without having to add them as a member on the connected boards.

Basically, it is a high-level board reporting the progress of different projects to the management. Few columns on the board are mirror columns connected to a few level boards. Adding members of management to all the low-level boards wouldn’t be an option, but without being subscribed to that board, they’re unable to view the mirror columns values.

We have added our clients on low-level boards as guests, so every project or client has a separate board.

What is the best way forward on this?

Adding screenshot of the board from member perspective.

Below is what we need them to see.
