I wanted to propose a copy collection items feature that would allow users to just copy all linked references in a collection and add it to another collection of the same type. For example, it would be possible to copy a list of attendees from one meeting entity and that same list to another entity. I know you are able to duplicate entities, but I think this need sometimes comes up after the entity has been created.
While this is UI function (through a button or keyboard shortcut), I also wondering if it can also be made available as part of the API. You currently have to write a loop to add items from one collection to another using addCollectionItem in each automation script. A single API call that abstracts this would be very useful.
