Is there a way to present in half-screen (for folks with ultra-wide monitors)?

Since I have a super-ultra-wide monitor (5120x1440, which is basically 2x normal wide-screen width aspect ratio), when I present to others (generally over Zoom) I actually want the presentation to only take up half of my screen so it will be the correct aspect ratio for most other people without letter-boxing, etc.

But if I actually use the full “Present” button, it always switches to full-screen.  Without that button, there are some extraneous elements on screen as I move through frames, which isn’t ideal.

Is there any way to make the presentation just take up half of my screen instead of the full screen?

If this can’t be done, should I do something else to request the feature, or will Miro pick up things from this conversation?

Thanks!
