Issue with Cart Override

[pooriaset]

Assuming an anonymous user adds products to their cart on our website and then logs in, we have observed that if the same anonymous user accesses the site via mobile and adds products to their cart again, the new cart items override the previous ones after logging in.

It would be better if the cart items from both sessions (desktop and mobile) could be merged instead of overriding.

Is this functionality possible to implement?

@pooriaset I haven't really put too much that into cart session collision behavior. I'm open to this being a toggleable options that would change the behavior like what you've proposed but implementation would take some investigation.
