Customize plugin to accept multiple product product sections

I am wanting to customize the plugin so that I can have multiple product sections. The way that the plugin is currently working is that I can just select any products from woocommerce and it will show up under the above text section(if applicable).

I am wanting to be able to add multiple sections. example,
Section 1 Above text: Shirts
Here I will have a horizontal grid of with 4 columns of shirts.

Section 2 Above text: Hats
Horizontal grid with 4 columns of hats.

Here is an example image: https://ibb.co/t400ChJ

Please let me know if there is a way that you point me in the direction of customizing this feature.

I don’t have a whole lot of WordPress PHP experience, but if I can be pointed in the right direction I may be able to figure it out.

Thanks,
Skyler
