Is it possible to change the island name

By right-clicking on goods in the warehouse or depot, you can set the minimum amount that is kept in stock.

Once you've set that, you can set a trade route to unload and then load from that port and it will keep the stock of that good at the amount you set as the minimum.

I did this in my sandbox game with just one "Building Materials" trade route. Using the Tycoon's ships that have 6 cargo holds, I had them set to unload then load the six types of building materials (building modules, tools, wood, concrete, glass, and steel) from each of my islands and had set a minimum on each island for these 6 goods. Set a handful of ships to the route and it worked pretty well.

Their demands consist of energy drinks, fish and Functional Food, they need to be in a range of a laboratory they have road connection to and finally taxes need to be at the lowest level.

You also must make sure that ascension rights are not disabled at your city center.
