Trying to implement "if A or (B and C)"

I'm essentially trying to implement "if A or (B and C)" condition logic for my player's shooting. Normally the player must press the z button to shoot a single bullet, but if they've purchased a 'rapid fire' upgrade, they can just hold down the z button and they will continue to shoot.

I'd like to implement the logic like this:

if (z button pressed) OR (z button down AND player.hasRapidFire = true) then [execute shoot logic]

However, I can't do this because C3 doesn't allow combining AND's and OR's in a single event. And because [execute shoot logic] is rather complicated, I don't want to duplicate it in a separate event or put it into a function.

Can someone please suggest a clean way to implement this condition logic?

You can use a variable for gun state.

State = 0 => on key Z pressed

State = 1 => on key Z down

...etc.

I like your suggestion, it's clean and it works. Here's how it looks in code fyi. Thanks!
