Hello, would it be possible to add placeholder text (or pre-populated text) to the 'New ticket comment' box in RSR warning in large letters that this comment is visible to the customer.

Currently we have the 'Don't email' button ticked so that we don't accidentally email a comment to the customer that we don't want them to see but on occasions the engineer forgets to untick the box and we think we've sent an email when we haven't.
