Here’s more context:
Team Member A fills out a form and indicates the date Team Member B should follow-up. This data from Team Member A is added to Board A which sends specific data to many other team members and boards, including Team Member B and Board B. The boards are connected and the date that Team Member B should follow-up is mirrored into that team member’s Board B. How can we notify Team Member B that the follow-up date is approaching since the date column is a mirror from Board A and not a “pure date” column native to Board B?
