The tool that can help you to solve this problem is called Facebook Auto Splitting. This tool can automate the process of ad sets creation when launching A/B testing for different audiences.

1. Manual creation of a large number of ad sets.
2. Generating several creative combinations for each ad set (for example, four images and two texts come out with 2*4=8 combinations)
3. Continuous results tracking (ideally, every hour)
