ability to control Bureau Approver email sending

The Bureau Approver emails are currently triggered when the 'Start New Pay Run' button is clicked.

Can this trigger event be changed to the press of the Finalise Pay run button?

Also, can there be more control over whether emails can be sent and the frequency of the sending of the Approver and related emails from Bureau.

Such controls would be very useful to avoid a volume of emails sent to the Bureau customers so that the key emails can be sent at the most relevant time.
