Under teams > Overview > Members - it's only possible to have one Admin/Billing contact. There is no warning that adding someone else as an admin removes it from the existing admin (secondary problem). We would like to be able to assign more than one team admin at a minimum, and be able to decouple the billing from an admin account if needed. We'd also like to see an RBAC (Roles based access control) method so that we could create roles and assign projects, functions (such as billing owner), and associated audit controls for specified activities. Happy to discuss more!
