The available types of Commands are configured on the Power Configuration object, on the Commands tab, as described on topic Standards for Command Types.

On Commands users can insert Command Units. By default, Discrete Commands are created containing a Command Unit, and they can have as many Command Units as needed. On the other hand, Step Commands are created with two Command Units and users are not allowed to insert other Command Units without removing the pre-existing ones. To insert Command Units, right-click a Command and select the Insert - Command Unit option.
