They've been busy over at WHQ these days, working on updating Unimatic to allow for specified nicknames to be displayed on the IBS.
According to the Briefing Packet dated Jan 15-31, Flight attendants "will soon be able to have their preferred name listed on the IBS. To do so, they must enter the name they preferred to be called on the FDMS nickname line."
This change will occur on Feb 12 and will look like this:
