Ad ID to menu button

but you can do something that will not disturb those menu-item-ids.
You can give an Id and Alt attribute to the anchor itself.

But i had to find a way that we will not have duplicate ids then – you see the problem if you put this to your child-theme functions.php

the (hamburger menu items anchors will have the same ids – and if the menu-link goes in a one-pager to that ID – . . . . .… etc. pp.
maybe it is on SEO Purpose more important to have only the alt Attribute to that link!!!:
Why must it be an ID that was tracked by Google Analytics? Arn’t there other possibilities.

function set_attributes_to_menu_links(){
?>
<script>
(function($){
  $(document).ready(function(){  
    $('#avia-menu .menu-item a').each(function(){
      var menuName = $(this).find('>.avia-menu-text').text();
      var customID = menuName.replace(/\s+/g, '_').toLowerCase();
      $(this).attr('alt', menuName); 
      $(this).attr('id', customID);    
    });
  });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'set_attributes_to_menu_links');
