Adding users to roles via AAD group

Currently, we have to add individual users to a role for them to allow access to Nintex platform.
In order to automate this process of access granting, why cannot we just add an AAD group to a role once and then keep on adding people to that AAD group for access granting.

This way we will never have to come back and visit User Management.

I believe this feature exists in K2 but not in Nintex Workflow
