I’m guessing the answer is no then ??

I’m using Elegant Zazzle plugin because I wanted the same thing. It hasn’t been updated in just over 2 years, but works. With a little css work and some other stuff, I found I got it to function exactly as I wanted. Different pages for different country stores with a redirect based on their country. The only thing is that they have hard coded their own affiliate id into the plugin, which you can over ride very simply.

I wrote this for the US. I will look into other countries.
