Android Studio中的Gradle子风格

Question

有没有办法在gradle中添加子风格？

例如：

productFlavors {

    production {

        whitelable1 {
          packageName 'com.bla.whitelable1'
        }

        whitelable2 {
          packageName 'com.bla.whitelable2'
        }

    }

    staging {
        whitelable1 {
          packageName 'com.bla.whitelable1.staging'
        }

        whitelable2 {
          packageName 'com.bla.whitelable2.staging'
        }
    }

}
