Try this (login//password is the same as FT)

Go to <Find Awards>
Select your dates and routing, and class of service.
Then click on the Star Alliance (Ana) tickbox
The outcome should be the availability that most *A FFP should see available to ticket as award.
Then ring Victoria and spoon feed them the routing you've found.

Last one: Singapore in premium classes is somewhat of a unicorn. Typically only available via their FFP Krisflyer (random events of such availability in other FFP have been reported)
