1. A method comprising: presenting on a display at least one view of a representation of a stimulation region and a first field shape group; presenting on the display an implementation toolbar having at least one implementation icon that controls how stimulation therapy is changed in a time domain from the at least one first field shape group to at least one second field shape group, wherein the at least one implementation icon is at least one of a play slow icon, a play fast icon, a pause icon, or a reverse icon; receiving input defining the at least one second field shape group from a user; receiving control input from the user via the implementation toolbar that defines the change from the at least one first field shape group to the at least one second field shape group in the time domain, wherein the first field shape group is associated with a first configuration of a plurality of electrodes different from a second configuration of the electrodes associated with the second field shape group; and determining, by a processor, one or more intermediate field shape groups between the first field shape group and the second field shape group for speed control of stimulation therapy change based on the control input, wherein the one or more intermediate field shape groups each have a specific set of electrical stimulation parameter values.
