Add various eta pi+ and eta V decay channels
B+ -> eta' [pi+ pi- gamma] pi+ B+ -> eta' [eta (gamma gamma) pi+ pi-] pi+ B+ -> eta' [eta (pi+ pi- pi0) pi+ pi-] pi+
B0 -> eta' [pi+ pi- gamma] rho0/Kst0/phi B0 -> eta' [eta (gamma gamma) pi+ pi-] rho0/phi, B0 -> eta' [eta (pi+ pi- pi0) pi+ pi-] rho0/Kst0/phi
