How to rewrite title- and meta-description templates for page templates in Yoast Plugin [closed]

Question

I am working on an project with many different page templates instead of custom post types. For SEO purposes I need to rewrite the title- and meta-description, which normally works on the page itself. Because of the impact of changing these titles and descriptions (1600 pages), I'd like to change the title- and meta-description templates for all pages with a custom page-template in the Yoast plugin.

Is there a way to rewrite the titles & meta's based on page template (page-[template-name].php) in the Yoast plugin?

I can use a filter to change title- and meta-description based on the php template itself, but it is not the best solution, because I'd still like to use the variables like %%sep%%, %%sitename%%, etc.

You may consider the use of both filter wpseo_metadesc (for meta description) and wpseo_title (for title). The idea is to change the values of title and/or description depending if you meet some condition.

So your code will look to somthing like this:

add_filter('wpseo_metadesc','custom_meta');
function custom_meta( $desc ){

    if (/* do your test here to check template or any other values*/) {
        $desc = "Change the description";
    } 

    return $desc;
}
add_filter('wpseo_title','custom_title');
function custom_title( $title ){


    if (/* do your test here to check template or any other values*/) {
        $title = "Change the title";
    }   
    return $title;
}

You can for example consider the function is_page_template() for your test.
