Onscreen Audio Monitor/FX

I am a noob as far as Resolve goes and must be missing something as Resolve seems to do everything else I could want (well almost!)

I want to "burn in" an audio meter into a video. Ideally I would like it to display peak levels as well as instantaneous level - ideally a PPM or LUFS scale. I thought it might be in the "burnin" options or video-fx but can't find it (if it exists).

Any advice or plug-in tips appreciated.

I don't believe this exists natively. If correct, you'd have to look for a plug-in which offers the effect.

That said, I know nothing about scripting, so...
