Maybe that's how Dave's version works with the cameras, I guess only he can say or someone else who has this one.
In Render Studio [sorry to keep mentioning it], which is a similar sytem, there are multiple cameras in the World browser.
I know that doesn't help, I'm just thinking that maybe Dave's works in that way, from the top menu bar...
I can't offer a solution for the teeth though, sorry..

Injustice will be avenged.
