Calendar Invites - send copy to approver/supervisor

Many of our supervisors/approvers manually add a note to their outlook calendar when they approve employee's requests for planned absence and training courses.  

It would be good if we could have an option to configure the calendar invite to also send an invite to the approver/supervisor at the same time that an invite is sent to the employee, possibly marked as an "All day event" so as not to interfere with the outlook  "Plan a meeting" functionality, or alternatively perhaps for 07:30 to 08:00
