Hi — are there any plans to offer an agency plan with the following features?

1. Ability to create multiple workspaces
2. Support for multiple domains per workspace
3. Signature generation (for users/teams)
4. Feature controls per workspace (for example: enable/disable branding and replace Swft branding with agency branding)
5. Agency billing tools — ability to bill clients, set renewal dates, and automatically suspend portal access if a client does not renew
6. Ability to customize card layouts and appearance
