Create a mutually exclusive study collection.
- Studies and study collections must be created separately and then added to the mutually exclusive study collection.
- Both the studies and the study collection must be in the same project.
- You can only add draft studies to a mutually exclusive study collection.
- Adding studies which are already in one study collection to another study
collection will remove the study from the original study collection.
