Subcategories and resource controllers?

Im using a resource controller to control articles.

/news

Hits the index method and brings up all the articles under the category.

/news/article-slug

Hits the show method and brings up an article under the category.

My question involves sub categories.

/news/sub-category-name

This would hit the show method which would look for an article with the sub-category-name when I want it to hit the index method and bring up a list of articles for the sub category.

What would be the approach to use for sub categories?

Add another route and method like:

get('/news/{subcategory}', [
    'as'=>'subcategory',
    'uses'=>'ArticleController@getSubCategory',
]);

Or would it be better practice to scrap sub categories and have a url like:

/news-sub-category-name/article-slug

Or is there another way?
