What type of app exactly are you building? A single app operates with a single database, but there are many ways to segment your data with custom data types and fields. For example, a geographic address field could do a lot to help break up users by country.
In the most general of approaches, you can have a predefined list of regions in your database under a Region data type. That type could contain a text field for the path (e.g. “UK” or “south-america”). You could create a condition like the following:
When page is loaded > navigate to external site > your app.com/search for region:first item’s path
Where the search has a constraint: country = current geographic position :extract country.
This is just one way to do something like that, but depending on your needs your set up might require other things.
