Hi Eddie,
Thank you for your feedback and great suggestion!
Currently, there is no option available to automatically apply a discount on item Y when item X is also in the cart. However, I completely understand the value of such a feature for upselling and bundling.
I’ve added your request to our feature wishlist. If management approves, it may be considered for a future update.
We truly appreciate your input — it helps us improve the platform for everyone. If you have any other suggestions, feel free to share them anytime.

Best regards,
