Hello @GNC,
If you would like to add a specific static block for each category, you can add content into the Description area for the category. You can select the position via Theme Options > WooCommerce > Shop > Shop page layout > Shop Page Banner Position, as the category description content takes the position option from there (see screenshot: https://ibb.co/ncLmbMd).
To do this, create a static block with the desired content and add it into the Description area for the category (see example screenshot: https://prnt.sc/HhirATNket-y).
We hope this helps. If you have any further questions, please do not hesitate to reach out.
Best Regards,
