We have multiple boards for our long-term project involving different products and teams. Our goal is to consolidate items requiring input from the client into a single "client board." Is there a recommended best practice to achieve this? Ideally, we would like to keep the tasks in their original boards while also "marking" them for sharing on the client board. Additionally, if the client makes comments, uploads screenshots, or takes any other actions, we want these updates to reflect in both the original board and the client board.
