OK - that's a very fair question!
Trying it now, Google and DuckDuckGo both operate the same. For some reason I was really struggling to get any UK pages to appear, even when adding "UK" to the search results - but I must have been doing something wrong, because when I searched for "Microsoft Power BI pricing UK" just now, the UK page was the first returned, and clicking on it took me to the UK version.
This would be a cool feature - but totally appreciate that it's a feature request, not a bug!
