Hi @xcsmall ,
So the site link you showed is what you want for your site, right? Unfortunately, this is impossible with our plugin.
But, you can combine this plugin with another one called WPC Linked Variation: https://ww.wp.xz.cn/plugins/wpc-linked-variation/
The two main options will be simple separate product. And you can add the list of Bought Together extra items in the Bought Together tab of each product.
Next, go to Attributes, create a common attribute for them and two terms. Assign one term to each product in the Attributes tab of each single product page.
Then, go to Linked Variation >> Add new and add two products, put a check on the above attribute to link them together.
In the frontend, they will appear as if they are variations of a variable product. When customers click on a button, they will be brought to the corresponding product page with the corresponding list of Bought Together items.
Remember, they are linked variation, not actually variations of standard variable products. But doing this, you will be able to link different products to each of them as Bought Together.
You can learn more about the other plugin here: https://doc.wpclever.net/wpclv/
Best regards.
