title: Write T4 generated code to separate output files
body: <p>I am creating a <code>.tt</code> file that transforms text into model classes, to practice.</p>
  
  <p>A <code>.cs</code> file is generated that with all <code>models</code>, but I would like each <code>model</code> to be saved in its own <code>.cs</code> file in a different folder.</p>
  
  <p>What would be the best approach to achieve this? </p>
