Add GM capability between sites 1&2 and 3&4 to 4 site replication enhanced solution

Currently the 4 site replication enhanced solution allows a client to switch from MM to GC between sites 1&2 or between sites 3&4. Typically this functionality would be used if the MM replication was causing a significant temporary production impact. This is a great feature. Since the 4 site session does have GM Journal volumes at all 4 sites, a feature to allow the user to switch from MM to GM between these legs would be an extremely valuable feature. Since DS8900F 9.4 microcode delivered multi-target GM capability, this would be a pre-requisite.
