Localise - Seperate screenshot for my primary location?

Hi Guys, I want to localise my app store product page. I want to have a default set of images for all product pages and for my primary location (Australia), I want my primary image to be different. I want to show that it is Australian-made.

by default your primary location becomes your default for all other images and I don't want the same screenshot in all other stores (US, UK,JPN etc)

Any ideas?
