I am working on scenery for Beijing. I have added the new terminal, runway, and taxiways. I would like to correctly name the new links, but in the properties' dorp down identifier menu, the letters I need are not there. I only get like A-Jwhich is only the identifiers used in the default airport, but I need the whole alaphabet. Is there any way to add available taxiway idents to AFX?

When you hit the drop-down box to the right of the yellow question mark, it will list available choices. Just type your new taxi designator in the blank area and AFX will ask if you want to add the new taxi name. Hit yes and name away.
