Can you put properties like fail-fast? true in the individual test config (not top level? Where am I going wrong here?

#kaocha/v1
{:plugins [:kaocha.plugin/junit-xml]
 :fail-fast? true
 :diff-style? :minimal
 :tests [{:id :integration
          :skip-meta [:migration :pagination :wind]}
         {:id :migration
          :focus-meta [:migration]}
         {:id :regression
          :focus [sqa.regression-test]
          :fail-fast? false}]  ;; <-------- does this not work?
 :kaocha.plugin.junit-xml/target-file "report.xml"}
