Bulk assignments
Setting access person by person is fine for one hire — not for a rollout. Organization → Assignments shows the whole matrix: members as rows, sites and groups as columns.

Reading the matrix
Section titled “Reading the matrix”- A checked box = the person is pinned to that site (or member of that group).
- An inherited box (greyed, not uncheckable) = the access flows down from a parent site — to remove it, it is the parent’s pin you must lift. The matrix shows inheritance instead of leaving it to be guessed.
Editing
Section titled “Editing”Click the boxes: every click saves immediately — no Save button, no “pending” state. You can sweep a whole column (“all of the Corbas warehouse for the morning team”) in seconds.
