We have three boards on a company-managed project and we need each board to capture the requirements for each product that we're working on for the same client. All the requirements are in the backlog of the project but we don't know how to add the requirements (user stories and tasks) to each board, each board should have different requirements because the products are different. Is there a way we can add a set of requirements (user stories and tasks) to a board and then add another set of requirements (different from the first set) to our second board?
