WooCommerce showing subcategories and products together

I’m using WooCommerce plugin in my WordPress site.

I’ve made some categories and I’m showing them in a wordpress page with the following snippet:

[product_categories parent="0" orderby="name" order="ASC" hide_empty="1" ids="1,2,3"]

Under the first category, I’ve also made 3 subcategories that I’ll call 1A, 1B, 1C to be more clear.

I’ve a lot of products of the “id=1 kind” and some of them belong to one of those subcategories and some other products belong to the parent category (id=1).

I’d like that when the user opens the categories page and clicks to the (id=1) category he can see, in addition to the three subcategories, also the products that belongs to id=1.

Actually, it is showing only the three subcategories and zero products of the parent category; I’d like to see together the subcategories and the products belonging to id=1, is it possibile?

thanks in advance for your help 🙂
