Alternate or destination change in FSX.

One thing I hope to see in FSX is the option for an alternate airport that you can ask ATC to fly to if the need arises. Holding patterns over airports I believe have already been covered here as well as SID/STARS.A big issue in FS9 is being able to request a destination change without having to go into the FS menu. It would be nice to get a list of airports (private and International) within a 100+ mile radius of the aircraft in the ATC menu. It sucks to be in mid-flight and have to stop the sim in order to request a flight plan clearance/change etc... :-)
