Джанго sitemap (карта сайта) вложенные url

Сижу над sitemap уже 3 дня. Пробовал разные схемы, но толком ни чего не нашел.

Все что есть на просторах интернета описано в моем примере ниже в функции Sitemap - это не подходит.

Нужно чтоб в карту сайта выводились url с вложенностью —

http://example.com/categories/,

http://example.com/categories/category-1/,

http://example.com/categories/category-1/post-1,

http://example.com/categories/category-2/

http://example.com/categories/category-2/post-2-1,

Ни чего подобного в решении такой реализации sitemap я не нашел ни в ютуб ни в документации ни на просторах google. Искал как на русском языке, так и на английском.

Те кто знает, подскажите как это реализовать. Заранее спасибо!
