title: Aggregating Gradle project-report reports for subprojects
body: <p>As per title, is there a way to have aggregated project reports for all the subprojects? In my build.gradle I have something like:</p>
  
  <pre><code>subprojects {
    apply plugin: 'project-report'
    // ... more stuff
  }
  </code></pre>
  
  <p>but then I end up with one report per subproject. It would be nice to have all the reports in one place but I couldn't figure out how. Is this possible?</p>
