Unfortunately, something like this isn't available in Fiddler. This is because Fiddler only works with HTTP/S and FTP/S or related protocols. If the traffic is not run on this protocol then Fiddler cannot "see" it. Let me provide more details for this scenario below.
When importing a Wireshark PCAP file, Fiddler parses the raw TCP/IP traffic and creates new sessions based on the HTTP/S traffic found within and anything else will be overlooked. Telling Fiddler that all traffic on a specific port is HTTP traffic will still need to be parsed into a new session.
I hope this helps. Please let me know if you need any additional information. Thank you for using the Fiddler Forums.
