Hello @PR,
We have created a video to demonstrate the process of creating attributes under Product >> Attributes and assigning them to variable products as per your requirements. You can view the video here: https://www.veed.io/view/091cbb06-6aa6-4873-9f47-fde5fa7adbe8?sharingWidget=true&panel=share
We also have a feature in our theme called Frequently Bought Together, which you can use as described in the documentation and in this video: https://www.veed.io/view/e34588ec-b059-4fb4-81c4-e7c8dd1122ad?sharingWidget=true&panel=share Alternatively, you may wish to consider using a third-party plugin that better meets your requirements.
We hope this information is helpful.
Best Regards,
8Theme’s Team
