There have been rumours about this for sometime, which have now been confirmed with the following message within users MCC.
“New! You can now assign three new access levels — administrative, standard, and reports — to other users in the account.This new feature increases security by allowing only administrative access users to grant, modify, or remove account access of other users. Also, this feature maintains privacy by ensuring recipients get email communications appropriate to the user’s access level.
If you are the primary administrator of this account, please take time now to set up access levels for all users in this account, as all users will have administrative access by default.”
