Geocortex Analytics autorization management - eg. based on ArcGIS Portal groups

Please implement any form of autorization management, with different roles.
Atleast 3 levels of acces I can identify:

• No Access
• Read-only - existing (main)dashboard
• Dashboard creator
• Admin

It would be easy to manage when Geocortex Analytics does not implement group/role management itself, but to connect it to group management in ArcGIS Online or Portal, so you can use the authentication and autorization of that platform.
