IAM permissions to allow/restrict access to dashboards

The idea would be to add groups that have specific permissions e.g viewer access to dashboard 1.
This would allow you to give teams a specific grouping and allow them access only to relevant information to them, currently we have around 15 dashboards and only 7 teams. Only 2 dashboards are relevant to each team and we would like to make it that they can only see the dashboards that they need access to rather than all dashboards in the company. Having group permissions and the ability to choose who can view a private dashboard would make this possible.
