16:9 Guides for Square Comp?

[entry-newspaper]

Morning!

I'm working in an oversized square comp - for purposes of greater latitude downstream in post.
However, I want to have a 16:9 view-port guide in Cinema. What would be the best way to accomplish this?
The Title / Action Safe lines won't help, because those are only a percentage of the comp, so they're remain square.
The RS Camera does have a number of optional guides, but none of them allow me to precisely show the 16:9 I desire.
I'm sure I'm just missing a native tool for this, but could someone please point me in the right direction?

Thanks so much!

You can use a Spline with 16x9 size as a child of your camera. Just move it slightly in front of the camera

Ha! That's the simplest solution. Thanks!
(I'm still surprised there isn't an option, within the camera guides settings.)
