If you have macro space you can create 5 macros to target each one of your group members. Bind the F1-F5 keys on each clone to these macros.

Or, if you are using AHK you can use sleight of hand to save on macro space. In AHK when you recieve a F1 you can send a F2 to the clones etc.

EDIT: Scrap the AHK comment as you are running multiple machines.
