Dual Management Control means that all the modifications on access rights and limits must be authorised by both Primary Users in order to take effect.
You need to submit the 'Business Internet Banking Authorisation Change Form' and the appropriate 'Board Resolution or Mandate for Changing Primary User Authority Type'. You cannot make the change online.
No, you cannot set up different levels of management control for the two Primary Users. However, you can set up different daily limits for them.
