Or, in Wireshark, through an option to annotate the capture after you've made it; File -> Save would be activated, and it'd write out a new version of the file with a comment option in the SHB.

For annotating the capture when you make the capture, I'd have a field in the Capture Options dialog, activated if the capture is being done as a pcap-NG file rather than a pcap file.

...and, in Wireshark, a dialog of some sort to let you add comments and save the capture out.
