Several methods exist to measure CP violation observables related to the CKM Unitarity Triangle angle $\gamma$ using $B$ meson decays. These observables are different for every $B$ meson decay considered, although the information they contain on $\gamma$ is encoded in a similar way for all of them. This paper describes a strategy for a simultaneous measurement of $\gamma$ using several $B$ meson decays that takes into account possible correlations between them. Sensitivity studies demonstrate that the simultaneous analysis of several $B$ meson decay modes results in smaller uncertainties and improvement compared to a combination of standalone measurements.
