Custom fields

[TryDevBetter]

There was a need to add custom fields for data export to clickhouse. I found information that there is an option --custom-fields which seems to allow this to be implemented. I don't have this option in the installed nprobe (version 10.7.240814). The task is to add a couple of fields with static data that are not taken from traffic but are simply set at the time of launching the traffic capture. Is it possible to implement it somehow?
