I have associated multiple contacts with my deals. When I look at the "deals kanban" view I can only see the first contact associated with that deal. In my deals pipeline I frequently get in contact with someone from a company, but later someone else becomes more important for closing that deal. Therefore it is important for me to change the primary contact that is displayed in the deals' kanban view during the lifecycle of a deal.

How can I change the primary contact for a deal that is displayed in the deals' kanban view?
