Hello Jbar, yes in that case it is indeed the option.
You need to do 2 things, use a data feed solution that can submit regional data, such as datafeedwatch
And you update your theme to allow the detection of region id, in the URL query string.
Before you start going too deep, first check if region availability is enabled in your account. If you don’t see the region in your GMC account, contact Google to enable it.
Is it enabled already?
