Force Region OAuth2?

Is it possible to "force" a request to go to a specific region? Many of our update scripts are extremely slow when updating data for our Australian clients.

I believe this is because our servers are located in London and the AU OAuth2 tokens are routing our requests to your AU server region.

I assume it would speed everything up to the same level as our UK customers if we could tell all of our requests to route to the EU region?

Hope its possible!
Cheers
