Important Notes about Integrated Events
The Host is set per integrated feed. This association of Event items to the Host that you have configured is applied during each sync. It is not possible to override this for specific items. The intention is for each integrated feed to be associated with a single Host.
Integrated Events cannot be set to use the Assessment functionality by default. If you enable “Assessment” for an integrated Event item, and that assessment receives an input (such as a check-in), then it will be considered a new item in the platform, separate from the integrated item. This is something you could do to divorce an Event from its feed. The caveat is that the Event will be created again from the feed, resulting in a duplicate. However, you can delete this duplicate, and it will NOT be recreated a second time.
