I work in sales, we use trello to manage leads, jobs, and as a CRM. I am looking to find out if there is a way to prevent duplicate cards or duplicate boards with the employees? For example we have employees A, and B. If employee A is pursuing company 1 and has them on their pursuit board but employee B does not look at employee A's board is there a way to prevent employee B from creating a card or board with company 1 as a lead or possible bid, or even a way to notify employee B that employee A already has company 1 on their board?
