Changes the rule's entities incrementally. add adds to the rule's include and exclude lists, and remove removes from them. Adding an entity that is already present, or removing one that is not, has no effect. A request with neither leaves entities unchanged.

The same entity cannot appear twice in one list, in both add.include and remove.include, or in both add.exclude and remove.exclude. To move an entity between include and exclude, remove it from one list and add it to the other in the same request.
