ui: Cannot specify custom ftrace events when recording trace

[ivan-chong]

I am trying to add an ftrace event to the config which is not listed in these preset groups, but I can't seem to find an option to do so.

[SergejIsbrecht]

Just do it manually in the "Cmdline instructions".

ftrace_config

ftrace_events: "custom/event"

You also need to enable: Enable generic events (slow) for custom ftrace events.
