basic question

I have been writing all my dissectors based on the port it will be 
broadcasting on. For example:

static int global_test_port = 11111;

void proto_reg_handoff_test(void) {
    static gboolean isinitialized = FALSE;

        if (!isinitialized) {
            testdata_handle = find_dissector("data");
            test_handle = create_dissector_handle(dissect_test, proto_test);
            dissector_add("udp.port", global_test_port, test_handle);
    }
    isinitialized = TRUE;
}

But what if I just wanted to make this dissector available as "decode 
as" and not by the port it broadcasts on..??

Can I just pass in a NULL for global_test_port..??

dissector_add("udp.port", NULL, test_handle);

Just wanted to see what the best thing to do is here. I was just simply 
going to pick a port that it would never be on...such as 11111.

Thanks,
Brian
