How to target multiple applications from same overlay package?

Question

I have a Runtime Resource Overlay(RRO) package with manifest as shown below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.myapplication">

    <application android:hasCode="false" android:theme="@style/Theme.Fluid.Dark"/>
    <uses-sdk
        android:minSdkVersion="29"
        android:targetSdkVersion="29"/>

    <overlay
        android:targetPackage="com.amazon.firelauncher"
        android:targetName="CarUiCodelab"
        android:isStatic="true"
        android:priority="1"
        android:resourcesMap="@xml/sample_overlay"
        />
</manifest>

Need some guidance to see how i can do the same?

I tried doing the same by adding one more tag however that didn't worked. Manifest example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.myapplication">

    <application android:hasCode="false" android:theme="@style/Theme.Fluid.Dark"/>
    <uses-sdk
        android:minSdkVersion="29"
        android:targetSdkVersion="29"/>

    <overlay
        android:targetPackage="com.amazon.firelauncher"
        android:targetName="CarUiCodelab"
        android:isStatic="true"
        android:priority="1"
        android:resourcesMap="@xml/sample_overlay"
        />
    <overlay
        android:targetPackage="com.android.settings"
        android:targetName="CarUiCodelab1"
        android:isStatic="true"
        android:priority="1"
        android:resourcesMap="@xml/sample_overlay"
        />
</manifest>

My aim is use the same RRO package to target multiple other apps too.

This is not supported as of today. You will have to create another RRO package to overlay the second target.
