Hi,
If you mean the name as it is displayed in the "Area Map", then at a quick glance, it should be possible. You would need to rewrite this part (in the areamap.xml) by the looks of it:-
<UIText name="AREA_NAME_TEXT" x=20 y=36 width="398" height=23 align=left valign=middle fontfamily="Body_Font" style="1" uppercase=false multiline=false update=true OnUpdate=UIText_OnUpdate_DisplayAreaName() />
You would probably have to disable this section and then write your own callback to display the name text (whatever you decide it to be) as a text sent to the GUI. i.e. A script that sends the "name" of your area to XML each time it changes.
Cheers,
Lance.
