Ability to mirror a board please!


Please add the ability to Creat a mirrored sub board that can have some colors removed! This a must for me and I see others have found complex work around but this would easily be solved with the ability to creat a mirror of a board.

Just to make this clear, not a duplicate board but a mirrored board that anything changed on one board would also be changed on the other, or have the ability to assign seniority to make one mirror to the next, etc.
