When you have multiple brands, currently the only option is to subscribe to multiple Agency accounts if you want to provide custom branding for different tradenames (DBA) tied to the same legal entity. In the real world, you would operate as separate public brands, so having only one legal entity as the main brand does not work. It would be great to have the ability to create API links, domain links, logos, etc. per DBA brand for the same legal entity instead of having to purchase multiple Agency accounts to provide branded app logins.
