title: Shopware 6: Is it possible (atm) to override or better extend an existing element (twig file) via plugin?
body: <p>I want to override or extend the element "image" ("..administration/src/module/sw-cms/elements/image"). Is it possible at the moment? First I want to extend or override the .../config/sw-cms-el-config-image.html.twig template, so I created the file in my plugin (MyPlugin/src/Resources/app/administration/src/module/sw-cms/elements/image/config/), but with no effect. </p>
  
  <pre><code>{% block sw_cms_element_image_config %}
      test...
  {% endblock %}
  </code></pre>
