Rewrite the markup of panels page title

Question

I'm trying to rewrite the output of the title of a panels page. I would like to add a class, for example. Actually, if I understand well, panels takes the layout from page.tpl.php then from the selected layout for its contents.
I tried to use taxonomy-term.tpl.php (I'm using the taxonomy page override by panels) but it doesn't work. Still, panels takes header, navbar and title styles from page.tpl.php.
Is there a way to avoid this? Is there a way to add a class or an id to the title element of a panels page?

Edit:
I found this which is for node_view panels template. I don't know if for term_view is different.

Following the comment on the panels issue linked in the question, I managed to make the panels page override for term_view works.
This is the code added to mytheme/template.php

function MYTHEME_preprocess_page(&$vars) {
  // if this is a panel page, add template suggestions
  if($panel_page = page_manager_get_current_page()) {
    // add a generic suggestion for all panel pages
     $variables['theme_hook_suggestions'][] = 'page__panel';
    // add the panel page machine name to the template suggestions
    $variables['theme_hook_suggestions'][] = 'page__' . $panel_page['name'];
        if($panel_page['name'] == 'term_view' ) {
           $vars['theme_hook_suggestions'][] = 'page__term_view';
}
}
}

Then, inside the mytheme/templates/ folder, I added page--term_view.tpl.php with my custom page title display.
