The extraction of Cabibbo-Kobayashi-Maskawa matrix element information from hadronic B decays generally suffers from discrete ambiguities, hampering the diagnosis of physics beyond the standard model. We show that a measurement of the rate asymmetry, which is CP violating, in B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathρ^\ifmmode±\else\textpm\fi\ensuremathρ0(\ensuremathω)\ensuremath→\ensuremathρ^\ifmmode±\else\textpm\fi\ensuremathπ+\ensuremathπ^\ensuremath-, where the invariant mass of the \ensuremathπ+\ensuremathπ^\ensuremath- pair is in the vicinity of the \ensuremathω resonance, can remove the mod(\ensuremathπ) uncertainty in \ensuremathα\ensuremath≡arg[\ensuremath-VtdVtb*/(VudVub*)] present in standard analyses.
