Hello @cbzhu! Thank you for being part of the Klaviyo Community! 🎉
Great question! Klaviyo's product feeds don't have a built-in option to display previously purchased products, but you can achieve this dynamically using an event-triggered flow based on the Placed Order metric.
You can check out another community post explaining this in detail:
🔗 How do I create a recently purchased block?
Or you can also check the Klaviyo Help Center article on setting up a replenishment flow:
🔗 How to create a replenishment flow
Hope this helped! Feel free to ask if you need further assistance. 😊
