Create new state
A new state name is created using the last selected state name.
Therefore, when you want to create a state name of a series, it is convenient to create a new state once the original state is selected.
When the tool creates new state's name, the tool uses the latest selected state's name. If the selected state's name has numbers of its end, the tool increments the numbers. If the state's name does not have numbers of its end, the tool adds a number '1'. If the same name state exist, the tool increments the number.
