We consider the possibility of studying the CP properties of various B(s) decays at an electro-positron machine tuned to the Upsilon(5s). Since decay modes of the B(s) with definite CP are relatively rare, we suggest that the use of more common modes which are not pure CP eigenstates may allow the determination of the CKM phase gamma. By studying the degree of correlation between different decay modes at a Upsilon(5s) it is possible to determine the degree of affinity of each decay mode to a CP eigenstate. Once this is known, the correlation between a decay mode with a greater affinity to a particular CP eigenstate with a mode such as D(s) + K- gives a determination of the phase gamma.
