Drop in one payload or an array of them. Each payload needs a bay number; it overwrites whatever is in that bay.
Copy this, set the bay number at the top, and hand it to the agent along with its task.
Point the deck at a URL that returns an array of payloads. It re-reads on a timer and updates any bay whose data changed.
A name helps you tell an agent what belongs here. Agents can overwrite it when they send data.
