While setting each remote Speedlight to a seporate group gives you more control over the lighting, the remote Speedlights do not have to be set in different groups. You can set any number of Speedlights to each of the two or three remote groups depending on the Master Speedlight that you are using.

One you get used to changing the settings, it will be much easier. Good Luck and Enjoy your Nikons!
