Customize title template based on page I know I can customize the template by overriding page-title.html.twig
but I'm looking for a way to have more than one title template. in my case, the suggested name form my path is  page__manage__customer_list So I tried to override it with page--manage--customer-list-title.html.twig. 
how is that possible to override the title template?

to make the question more generalize and could be useful for other guys that looking for similar circumstances this could be helpful.

How can I override the title template based on content type or route?
You can add new templates to already existing using hook_theme_suggestions_HOOK_alter

Example of adding a content type:

/**
 * Implements hook_theme_suggestions_HOOK_alter().
 */
function THEMENAME_theme_suggestions_page_title_alter(array &amp;$suggestions, array $variables) {
  if ($node = \Drupal::routeMatch()-&gt;getParameter('node')) {
    $content_type = $node-&gt;bundle();
    $suggestions[] = 'page_title__' . $content_type;
  }
}


Then use page-title--content-type.html.twig



You could use $node-&gt;id(); if content type is too broad.
