Adding a plus 1 to Joachim Halse above.
Similarly, I’ve been interested in configuring permissions by user (e.g. when adding User A I provide them view access only to Project B and Insight Feed C) but have not been able to solve for this. I’ve found configuring permissions on all projects to exclude user-by-user to be a daunting task when we have a large number of projects happening concurrently and a wide range of viewers on that differ from project to project.
