Abstract: We show that any linear map on a finite dimensional CSL algebra $\mathcal{A}$ which at each point is equal to the value of some automorphism of $\mathcal{A}$ is either an automorphism or can be factored as an automorphism and the transpose of a self-adjoint summand of $\mathcal{A}$. New examples of local mappings are constructed.
