Adding Tons of Content to Product Category Pages

Hi,

I’m starting to see it may be in my best interests to do seo for my product category page rather than each product page.

Therefore I am trying to add content to my woocommerce product category pages. I can see there is a description box that inserts text at the top of the product category page — which is fine for a sentence or two.

However, I am wondering if there is a way I can also add more text underneath the products/at bottom of the category page?

Basically I want to stick a 1,000 word article underneath my product pictures on my product category page — like a secondary description box.

How can I do this? Is there a plugin? I’d want it different for each product category page.
