It should be possible to assign additional domains to an existing cookie banner that can be used for testing and staging environments. I realize that the problem can be solved if the test and staging domains run as subdomains under the main domain of the production banner. But it should also be possible to attach other top-level domains for use in test context. Cookie Script can simply put an “only for testing” overlay over the banner so that it is not misused to apply the same banner to multiple sites.
