Would it make any sense to be able to store "application specific" information in a pcapng file ?

E.g., selected Wireshark prefs so that Wireshark can act on same ?

This would be useful when a capture file reqires specific dissector
preferences to properly dissect the file.

Would this fit (at all) within the design goals for pcapng ?
Is there be a way to do this reasonably cleanly with the existing format ?

How might one indicate the prefs which should to be stored ?

First thought: Keep a list of protocols in the capture file. For each, store only the preferences (if any) for that protocol which don't have the default value.
