The ability to create account/pages for my clients, under my own brand/custom domain and giving them access to login to manage calendar, upload videos, etc.

UPDATE: We are rolling out multi-team functionality soon that will allow:
- Creation of multiple teams/workspaces each with their own name, branding and invites
- Separation between all teams (members of a team can only see/access their own team)
This will enable you to maintain a separation of workspaces for multiple clients/businesses.
This update will be released in the next 1-2 weeks.
