投资组合类别为slug-Wordpress

我正在学习php&wordpress，但这是我所不知道的。我有一个投资组合的主题，我想分离SEO pourposes。

我有这个。（productos是当前的投资组合slug）

website.com/productos/portfoliopost1 (category-a slug)
website.com/productos/portfoliopost2 (category-b slug)

但我想展示的是：

website.com/category-a/portfoliopost1 (category-a slug)
website.com/category-b/portfoliopost2 (category-b slug)

有可能吗？谢谢大家。这是生成段塞的当前portfolio.php。

if ( !function_exists( 'pexeto_register_portfolio_post_type' ) ) {
/**
 * Registers the portfolio custom type.
 */
function pexeto_register_portfolio_post_type() {
    //the labels that will be used for the portfolio items
    $labels = array(
        'name' => _x( 'Portfolio', 'portfolio name', 'pexeto_admin' ),
