Both have moving nest capability. The preset moves require the user to know a point where the feature of interest will be moving, and to specify a set of increments to the nest location that will allow the nest to stay centered over that feature. It is doable, but time-consuming. The vortex-following option makes the nest automatically adjust its position as the vortex moves, by following the center of low pressure. This can only be used to follow a tropical cyclone.
