[otrs] Deleting an entry from a Ticket

Is there a way of deleting a single entry from a ticket and leaving the rest of the thread intact? A customer has just opened a ticket on my system and I have several staff users set up to be notified of this. My problem is that one of the staff users was on holiday so his "Out of Office" message was sent back to OTRS. This has resulted in the Out of Office message being added back to the original ticket as customer input and changed the title of the ticket to "Out of Office" I need to remove this single message and restore the ticket title....
