1. A method of programming an implantable pulse generator (IPG), comprising: providing a graphical user interface (GUI) screen on a programmer device, the GUI screen comprising (i) a master amplitude GUI control for selecting a master amplitude value from a plurality of amplitude values for a stimulation program comprising multiple stimsets, wherein each stimset comprises first, second, and third amplitude calibration parameters and an electrode configuration and (ii) multiple balancing GUI controls where each balancing GUI control directly controls the first amplitude calibration parameter for a corresponding stimset of the stimulation program; communicating one or more commands from the programmer device to the IPG to change the amplitudes of generated pulses for all stimsets of the stimulation program in response to manipulation of the master amplitude GUI control by a user of the programmer device, wherein the amplitude of each stimulation set is automatically calculated by a selected master amplitude value from the plurality of amplitude values and the first, second, and third amplitude calibration parameters of the respective stimulation set; automatically recalculating amplitude calibration parameters of a stimset corresponding to a manipulated balancing GUI control, the first amplitude calibration parameter of the stimset being assigned a value in direct relation to a level of the manipulated balancing GUI control, the second amplitude calibration parameter of the stimset being assigned a value as a function of the recalculated first amplitude calibration parameter and the third amplitude calibration parameter; and communicating one or more commands from the programmer device to the IPG to change the amplitude for pulses generated for a respective stimset of the stimulation program in response to recalculation of amplitude calibration parameters for the respective stimset.
