Neurostimulation systems (10) and control systems (16,18) for providing therapy to a patient are provided. Electrical stimulation energy is delivered to a tissue region in accordance with different stimulation parameter sets. The delivered electrical stimulation energy is incrementally transitioned through a first series of the different stimulation parameter sets at a user-defined rate in response to a single user actuation of a control mechanism. The user-defined rate is adjusted, and the delivered electrical stimulation energy is incrementally transitioned through a second series of the different stimulation parameter sets at the adjusted rate in response to a single user actuation of the control mechanism.
