Ability to modify product_category html before rendering

Not possible to extend product_category description using hooks.

My use case – I have additional field in my product_category page (description field before shop and one additional description after). I want to combine them in TOC.

Currently script overrides content value before processing, but gives no chance to modify it (i.e. append data from separate field).

    if(function_exists('is_product_category') && is_product_category()){
        $term_object = get_queried_object();           
        if(!empty($term_object->description)){
            $content     = $term_object->description;
        }                       
    }       

Something like that would be better:

    if(function_exists('is_product_category') && is_product_category()){
        $term_object = get_queried_object();           
        if($term_object) {
            $content = apply_filters('ez_toc_modify_product_category_content',$term_object->description);
        }
    }
