Set a default hover effect on overview pages (WooCommerce)

Dear Support Members, I am curious if there is a way to set a default setting for the hover effect on overview pages? On every product page I have a meta_box with settings for the hover effect:

Hover effect on Overview Pages
Do you want to display a hover effect on overview pages and replace the default thumbnail with the first image of the gallery?
• Default: No hover effect
• The other option is: Yes – show first gallery image …

For my pages I use a altered code form your documentation (mentioned in #1341086):

add_action( 'after_setup_theme', 'ava_enfold_builder_layout_mod' );
function ava_enfold_builder_layout_mod(){
  if ( is_page() ) {
	add_filter('avf_builder_elements', 'avf_enfold_builder_layout_settings_mod');
  }
}

function avf_enfold_builder_layout_settings_mod($elements)
{
  $counter = 0;
    foreach($elements as $element)
    {
    if($element['id'] == 'header_transparency')  {
            $elements[$counter]['std'] = 'header_transparent';
        }
        $counter++;
    }
  return $elements;
}

So could I write something like:

add_action( 'after_setup_theme', 'ava_enfold_builder_layout_mod' );
function ava_enfold_builder_layout_mod(){
  if ( is_product() ) {
	add_filter('avf_builder_elements', 'avf_enfold_builder_layout_settings_mod');
  }
}

function avf_enfold_builder_layout_settings_mod($elements)
{
  $counter = 0;
    foreach($elements as $element)
    {
    if($element['id'] == 'product_hover')  {
            $elements[$counter]['std'] = 'hover_active';
        }
        $counter++;
    }
  return $elements;
}

I already did some tests, but with no success. My goal is to set the default to “yes” for all new products. Any chance to do that?

Cheers, Daniel
