Currently, there is no one-touch mechanism to enforce on more than 2,000 messages at a time. In order to enforce on more than 2,000 messages you will need to break your search query up into smaller searches. This can include changing the date, sending domain, or any of the other search criteria.
You can also create a custom CDR event that will look for any previous and ongoing campaigns that match your custom event. More information about creating custom CDR events, see How can I create custom CDR rules with advanced DSL search queries?
