Thanks, BRONK!
But, yuck. I really can't imagine many situations where I'd want only one bomber gun to fire. And I don't want global fire all guns to mess with my fighter gunnery.
Fire from all gunners ought to be the default with the primary trigger (as it used to be.) Fancy Annie Oakley one-gun-bomber shooting ought to be selectable by different mode, etc. for those who'd actually want to bother with it.
