If you are in the previous version then you can write an activity and call Work-CorrNew activity which takes the To_PartyRoles parameter[Comma-delimited list of party-specific roles for To field (in addition to the Target party)]. Hope this might help you to achieve your requirement.
Create Decision Table with operators and correspondence logic. Call this in an activity and set correspondence name in a parameter and use Property-set-corr in next step and pass this parameter to set Corrstream.
I've configured a send email smartshape and specified a correspondence rule for one operator.
Then I added one more send email smartshape and specified Party role as Owner (So that I can send to different operators who initiated the work object).
After that created a correspondence rule for one operator and circumstanced that rule based on pxCreateOpName property.(Here based on the circumstanced property the two different correspondence will be sent).
