Events copied using Crew Manager Import Events are linked to the original event so that any custom field updates on the original event (e.g. an Amendment to the NOR is posted) are automatically pushed to the copied event. A background task checks all sites hourly and pushes any updates made on the original event to the copied events each hour. Race results are excluded from these updates. This also occurs if a repeating event is split. Any custom fields updated on the master event are automatically pushed to the split events.
Below shows the custom field added with the link protocol back to the original event.
