Is it possible to create a workflow from one store to another?

My website is currently setup for the buyer to choose a gift box in one store and once they have added it to their cart and they access the cart page, a pop-up asks them if they want to add extras to their gift box. They need to click on a link to take them to the extras page (another store page) or they can close out of the pop-up and check-out. Ideally, I would like to workflow the process whereby once they add the chosen gift box to the cart, it automatically takes them to the extras store page so I am not relying on them to access it themselves. Is this possible in Wix Editor or with coding? For clarity, the extras have their own pricing hence why they are listed as products in their own right. Thank you
