Sadly, you can't do this yourself. Just ask a QAT to change it. They're the only ones that are able to, so just give them a note of what you need/want, and if it's reasonable enough, you'll get your new title text on your map! Easy, right?!
If used correctly, it can add a certain effect (in a good way!) to a map. It changes the presentation of your map in an effective manner if used correctly by changing the elements and the time of the appearance of the title. If you're a storyboarder, this might be a very huge benefit to you!
Send a PM (private message) with this to a QAT member.
