Many items such as ammunition or raw materials will certainly be used, transported, or stored in large amounts. Worry not, because you have the possibility to split a huge stack into several smaller stacks to handle them easier.
You can set both the number of items to be divided (first text area), and you can also adjust exactly how many groups you want to create by giving the number of stacks.
The remaining items which haven't been divided into any stacks will automatically generate another stack. (For example, if you have 5 million Nian Rubber Ducks, and want to divide 4.5 million of them into three stacks, your end result will be three stacks of 1.5 million, and the other half million that weren’t part of the division process will be in a fourth stack. That’s a lot of fowl!)
