We would like to be able to create "events" that correlate with the release of material. Currently, you can expire material from a collection, but we would also like to be able to release material on a specific date which can be entered in advance.
This would be convenient for product/brand releases, temporary of seasonal things (anything with a defined date range).
This would be great if we could release or retire Collections, sections, Pins etc.

Let's say there is a set of material you want available over Summer 2018. You could set a release of June, 1 2018 and a retract at Aug 30, 2018. Advanced planning can help clean things up and give some tighter control of material (avoid material being available too long etc.)
