License Admin

As an administrator I would like to be able to control the use of licenses across my organisation by applying a limit to each license type. e.g. if we have 20 model builder licenses the system should stop workspace admins from assigning more than 20. I would also like to see something in Tenant Admin which would advise us of when users last used Anaplan and which model they used, and/or conversely telling us when a model was last accessed so we can see what is and isn't being utilised.
