Assign Users to Brands w/ Default Signatures and Help Center

When managing multiple brands in one Intercom instance, it would be helpful to assign users within Intercom (internal employees) to specific brands. That way, when they send emails, it would use the default email signature associated with that brand, and when they send articles to customers through Intercom chat, the default help center that shows up would be associated the Help Center for that brand, rather than the default for the organization.
