I imagine what Cirstea is asking for might be implemented easily if "Decode As" could be used to specify a range of UDP ports (say 500-599) as a certain protocol?

"Automatically" in what sense?
I.e., where do you find out the range of ports?
If there's some other protocol that has messages indicating that certain
ports are used for RTP and RTCP - RTSP, for example - and RTP and RTCP
will be running over UDP, for example, then you'd do it the same way the
RTSP dissector does it, i.e. you'd construct a "conversation", given
the IP addresses of the hosts that will be exchanging RTP and RTCP
messages, and the port numbers being used, and specify that the RTP and
RTCP dissectors should be used for that conversation.
