Not that I have ever *cough* used such an application, but a little birdie tells me that the aforementioned feature you are looking for may be combined with a *cough* certain mac application. This application may also be used when certain users want to automate other actions of their wow life. *wink*
You may wish to google the word 'pocket' and the name of the alliance race that hasn't got its own starting area.
Good luck with your endeavours.
Ps. I hope I was discrete enough.
This information is all from that kind birdie remember :P
