Method and systems for determining a set of stimulation parameters for an implantable stimulation device include performing the following steps or actions: receiving a stimulation target determining a target stimulation field based on the stimulation target receiving a weighting for a plurality of spatial regions defined relative to a lead including a plurality of electrodes, where a weighting for at least one of the spatial regions is different from a weighting for another one of the spatial regions and determining, using the weightings for the plurality of spatial regions, a set of stimulation parameters to produce a generated stimulation field that approximates the target stimulation field.
