Can I create units per location or region for a switchback test?

I want to create units by location in my switchback test. Is that possible?

No. At this time, it’s only possible to create units based on time duration (in minutes). To represent different locations, we recommend serving regions with different instances and doing parallel switchback tests.

To later merge the results of multiple switchback tests you can use the json endpoint to get all run data for each test programatically or export the data manually to CSV in Console.
