Refactoring plan:

• extract permanent customizations into separate storage/container so to allow multiple configurations (lets say, per fixture etc.);

• extract main functionality from static class into something (session?/factory?) that can be instantiated and configured (with permanent customizations container, see above) per scope/fixture;

• add support for lists creation (some already exists) and customization (list as a whole & each item)

• publish as a NuGet package
