There are two ways to create a rule. You can either clone (copy) an existing rule or create a new rule from scratch. Cloning is the simplest and quickest option, as you base the new rule on one that is already in your list, taking advantage of existing brackets and so on. Even though the rules have the same names as the originals, they all have unique identifying numbers behind the scenes. You can then edit the setup of the cloned rule, as required.
