Presentation Mode - Ahhh filter

I am looking for a "Presentation Mode" feature that works like this:

- I notify Zoom that I would be presenting, so that Zoom knows it can buffer a few short seconds without annoying the audience too badly.

- When I say "Ahh" and "Hmm", Zoom will remove them - and having a few short seconds of buffering would make the job easier.

- Ideally, Zoom should smooth out the audio a bit... which is why I think the few short seconds of buffering is useful.
