When you create multiple rules at the same time, each rule gets the same setup and their default names and descriptions are generated in the following way:
The names and descriptions of the rules are very similar, differentiated only by the entity name. This is illustrated in the following example, where the first rule is called Region - QLD - Rule 1, the second is called Region - TAS - Rule 1 and so on.
You can edit each individual name and description later, in addition to changing any of the original setup.
