How to set signingConfig for different flavor dimensions?

Question

I'm trying to figure out how can I specify a signingConfig for the individual flavor dimensions generated. I have seen how to do it when using different flavor but not flavor dimensions.

I'm currently applying a different package name for the different flavor dimensions successfully and thought maybe something similar could be done with signingConfig?

>     def mergedFlavour = variant.getVariantData().getVariantConfiguration().getMergedFlavor();

>     if(flavorString.equalsIgnoreCase("amazonFree")) {
>         mergedFlavour.setApplicationId("com.test.amazon.free")
>     }
>     if(flavorString.equalsIgnoreCase("amazonPro")) {
>         mergedFlavour.setApplicationId("com.test.amazon.pro")
>     }
>     if(flavorString.equalsIgnoreCase("googleFree")) {
>         mergedFlavour.setApplicationId("com.test.google.free")
>     }
>     if(flavorString.equalsIgnoreCase("googlePro")) {
>         mergedFlavour.setApplicationId("com.test.google.pro")
>     } }

My flavor setup

// Special flavor dimensions for different markets and
// versions paid and free.
flavorDimensions 'market', 'version'

productFlavors {
    amazon {
        flavorDimension 'market'
    }
    google {
        flavorDimension 'market'
    }
    // Base free version
    free {
        flavorDimension 'version'
        // Need this cause of all the ad libraries we are using :/
        defaultConfig.multiDexEnabled true

        // For now we sign all free versions with this config
        // cause we have no idea how to sign the individual flavor dimensions.
        signingConfig signingConfigs.googleFree
    }
    // Base pro version
    pro {
        flavorDimension 'version'

        // For now we sign all free versions with this config
        // cause we have no idea how to sign the individual flavor dimensions.
        signingConfig signingConfigs.googlePro
    }
}

First of all applicationId can be applied in productFlavors block itself:

productFlavors {
    amazonFree {
        applicationId 'com.test.amazon.free'
    }
    amazonPro {
        applicationId 'com.test.amazon.pro'
    }
    googleFree {
        applicationId 'com.test.google.free'
    }
    googlePro {
        applicationId 'com.test.google.pro'
    }
}

Signing config can be configured per flavor the same way:

productFlavors {
    amazonFree {
        applicationId 'com.test.amazon.free'
        signingConfig  signingConfigs.amazonFree
    }
    amazonPro {
        applicationId 'com.test.amazon.pro'
        signingConfig  signingConfigs.amazonPro
    }
    googleFree {
        applicationId 'com.test.google.free'
        signingConfig  signingConfigs.googleFree
    }
    googlePro {
        applicationId 'com.test.google.pro'
        signingConfig  signingConfigs.googlePro
    }
}
