Hello Piotr,
Thank you for your suggestion. We value your input and appreciate your feedback.
We have a feature in our theme that is similar to what you have suggested, called “Frequently Bought Together”. You can find more information about this feature here: https://xstore.helpscoutdocs.com/article/132-frequently-bought-together.
If this is not what you are looking for, we suggest that you post your idea on our taskboard at https://www.8theme.com/taskboard/. If it receives enough votes from other customers, our development team will consider adding it in one of the upcoming updates.
Best Regards,
8Theme’s Team
