This can be done using the setoutletassist function. Example from the docs: function describe_it(num) { assist("this is outlet number",num); } // global code to set it up setoutletassist(-1,describe_it);

To set each outlet individually, you could simply write more than one 'describe_it' functions, and map each one to a specific outlet number (rather than using -1 as the outlet number from the docs example)
