Today, we must specify the exact collection name on which a policy rule is applied or omit it entirely in which case the rule matches all collections. In case a rule must apply to a subset of collections, before we create a new collection, we must copy over the rule with the collection name changed to the new collection.
It'd be nice to have a selector for collections based on the collection property.
The above rule matches all collections which have property_name set to property_value as a collection property. This makes it possible to add just one rule and have it apply to all collections having the property.
