Hi all!
Firstly, we sincerely apologise for the delay in updating you all. We are working on a process to improve our responsiveness, so really appreciate your patience and understanding in advance.
As for this particular feature, we have noted all of your comments and ensured this has been flagged for review. The team is aware that the functionality of the mirror/connect board column in general needs improving, so please be assured that this feedback is incredibly valuable to us. In full transparency, as of now, we cannot provide a concrete update on this feature, particularly supporting bulk select of a group or board, however we have followed up internally and once provided with more information to share, we will circle back
