Optimise for cost effective delivery

Hello. Help me find the answer to my question. Perhaps I will install on Opencart (optimization for cost-effective delivery) both on the site [login to view URL] The current Opencart basket shows only the number of products added. We must indicate the total weight of the basket. The speed of delivery depends on the weight, and visitors should be able to see the total weight, because the goods are added to the shopping cart. This delivery optimizer is the type of thing we are looking for: [login to view URL] 1 If you choose a country, you will be given a "container" with a fixed shipping price (say, 20.00 pounds sterling). Then you can add more products until the "container" is full. When you fill out "Container 1", it goes to "Container 2" and adds another shipping cost (£ 20), which is 40.00 pounds for 2 "Containers". From the user's point of view: every time a user adds an item to his basket, he receives a modal rectangle with the added product, the total number of items in the cart and a visual representation of how full the current container (for example, the progress bar), the user can continue the purchase or visit your shopping cart. When a user visits his shopping cart, they must select the country to send on the next page, for example: France. When they have chosen the country, they are sent to the page with the message of their order in "Container 1" (Max Weight: 25 kg) - Shipping 9.99 pounds. If they continue to make purchases when they fill out "Container 1", additional items are added to the additional "container" (container 2), and the delivery is doubled - (Max Weight: 50 kg) - shipping 19.98 euros. From an administrator's point of view: be able to change the maximum weight of the container The administrator can change the cost of shipping each container to different countries. For example, shipping a container to France will cost 9.99 pounds sterling, sending a box to the US will cost 19.99 pounds sterling - an administrator can easily change it in the admin panel. The visual representation of the container as a UK corner store, see In the image: [login to view URL], to appear on the basket page and in the modal window when the user adds the goods to the basket. Please tell me, is it really possible to do this?
