We illustrate the basic notions of \em additional non-isospectral symmetries and their interplay with the discrete \em \DB transformations of integrable systems at the instance of \em constrained Kadomtsev-Petviashvili (\cKP) integrable hierarchies. As a main application we present the solution of discrete multi-matrix string models in terms of Wronskian \t-functions of graded SL(m,1) \cKP hierarchies.
