At the moment this remains unchanged and as you would have seen in the forum post, you would need to look into the apps or into upgrading your account to have carrier calculated shipping.
What country are you based in? It is just that in case you were based in the USA, this may not be ideal but you can break down your shipping rates by states which can be separated into shipping zones by going to Settings > Shipping and delivery, click Manage rates and then CreateShipping Zone:
Another example of a country where you can break down your rates into regions is United Arab Emirates.
As I mentioned early, the above may not be ideal or even applicable to you depending on the country that you’re based in, so please do tell me a little bit more about why it would be important for you to break your shipping fees down depending on the city that the order is going to, and I will see about sending this feedback along to our developers on your behalf so that we can hopefully see something like this in future.
Have you offered your question on forum in git hub or a site like that for
developing help for yourself and Shopify I know this is obvious.
I’m not a developer but have access to git hub and forums.
I hope that this reply get you better attention here anyway.
Since you’re looking into local delivery, you might find integration with GrabExpress or MrSpeedy helpful. We have an app that you can add that allows you to book on-demand couriers with just a tap of a button. See it here: https://apps.shopify.com/restaurant-alerts-delivery
