verbose decoding without assigned port number

Hello, list.

There are network protocols that have an assigned port number, and there are other that don't or are commonly used on 
non-assigned ports, such as HTTP on port 8080. Looking at function tcp_print() in file print-tcp.c, it is clear how the 
former are handled, but is there any assumed way to handle the latter? I am considering adding a ZeroMQ decoder to 
tcpdump, to be particular.
