I have board A that contains a client name and various products that they’ve bought with us. In other boards, I track each purchase by products i.e. 1 board is the tracker for 1 product.
What I’d like to do is create a main item in the product board and it updates Board A each time a client buys a product, add that to Board A as a sub-item clubbed under the respective client main item. They are connected boards.
