Hi im building a project management flow with Trello. Currently, I am planning to have each team member to have their own respective board. Each teammate will eventually complete a card and then send to a QA. The QA has their own board as well. However, for a team member to send a card to the QA board, he/she must be a member of that board (QA board). I don’t want the team member to have visibility of the QA board. Is there a workaround to this? Or is there a way to limit member of a board to see only specific lists or cards?
