title: Assign separate entrypoint scripts to separate HtmlWebpackPlugin instances
body: <p>Given an entry/output like </p>
  
  <pre><code>entry: {
      app: 'src/client/app.js',
      unauthApp.js: 'src/client/unauth.js'
    },
  output: {
    path: 'dist',
    filename: 'scripts/[name]-[chunkhash].js'
  },
  ...
  plugins: [
    new HtmlWebpackPlugin({
      filename: 'views/index.html'
    }),
    new HtmlWebpackPlugin({
      filename: 'views/index-inauth.html'
    })
  ]
  </code></pre>
  
  <p>is it possible using two instances of <a href="https://github.com/jantimon/html-webpack-plugin" rel="nofollow noreferrer"><code>HtmlWebpackPlugin</code></a> to put the <code>app</code> script into one template and the <code>unauthApp</code> script into the other. So far all I have been able to do is put both scripts in both. I'm also playing with using <code>htmlWebpackTemplate</code> so perhaps there is an option there I have not seen.</p>
  
  <p><code>webpack@^4.6.0</code></p>
