We describe a method for measuring CP-violation parameters from which the Cabibbo-Kobayashi-Maskawa angle \ensuremathγ may be extracted. The method makes use of the total decay rates in B^\ifmmode±\else\textpm\fi\ensuremath→DK^\ifmmode±\else\textpm\fi decays, where the neutral D meson decays to multibody final states. We analyze the error of the method using experimental CP-violation analysis variables that enable straightforward sensitivity comparison with other methods for extracting \ensuremathγ, and discuss the use of B-factory and charm-factory data to obtain the relevant charm-decay information needed for this measurement. Measurement sensitivities are estimated for the currently available B-factory data sample, and D decay modes for which use of this method can make a significant contribution toward reducing the total error on \ensuremathγ are identified.
