you can add output sockets by name or even regex, they don't need to be 
currently active client/ports at any given time, just actual names need 
to match when they are.

for instance, say that your system output ports resemble Emanuele's, you can

1. add one output_socket_1 for system playback ports out_1 and out_2;
2. add a second one output_socket_2 for same client name (system) ports 
out_7 and out_8.
3. then edit output_socket_1 and set it forward to output_socket_2.

save and activate this patchbay profile.

from that moment after anything connectes to system:out_1,2 (main outs) 
will automagically also connect to system:out_7,8 (headphones in 
Emanuelle's example).

hth.
cheers
