This is a result of our system architecture. The customer level is the highest level in the system, followed by the account level with varying contact portfolios per account. The existing response and reporting data of an account would be lost after such a reorganization.
Furthermore, problems would occur for users with shared resources. However if you wish to have your account structure or hierarchy changed we will happily handle this for you: just contact your service partner.
