Delayed Membership Rules
It would be useful to be able to add a new rule to a collection that does not take affect until a set time. For example, when a collection for software distribution has an advertisement associated to it, you might want to schedule another distribution by adding another collection that includes another group of devices. Right now we accomplish this by creating a new advertisement. It would be better if we could simply link a new collection specifying a date/time that the collection would become available to ingest the existing advertisement.
