Using group-theoretical methods and numerical simulations, we show how to act on the topological charge of individual vortices in Bose-Einstein condensates by using control potentials with appropriate discrete symmetries. As examples of our methodology we study charge inversion and vortex erasing by acting on a set of control-laser Gaussian beams generating optical dipole traps.
