In some cases, you may want an Ephemeral Environment to persist for a much longer period of time, maybe for a sales demo or a really large overhaul of your product. In this type of scenario, we allow you to customize the expiration when you manually create a single environment. For example, on the Environments List screen, you can click the CREATE ENVIRONMENT button and a modal will appear. Open the Advanced Options toggle and you'll see the Environment Persistence settings.
