I am looking to book award travel (I have almost 500K united points but haven't tried to spend them in a couple of years) ATL-AKL leaving Jan4/13 (date is flexible) returning about 2 weeks later. Presently there is no award availability for the whole month of Jan and almost the first 2 weeks of Feb in any class whatsoever (I'm assuming/hoping it just hasn't been loaded yet and something might show up in the next few months).

I started playing around with united.com and found that there is availability ATL-BKK via ZRH, and also BKK-AKL for the dates I want, but I would have to do it with two separate awards.
So my question- is there any way for force the whole ATL-EWR-ZRH-BKK-AKL route in just one award? I have called United CS and so far no on ein the India call center can help or give me an answer (I haven't spoken to any U.S. CSR so far).
