What I do is select the camera that I want, select the frame, and press CTRL+B over the timeline, or "Marker>Bind Camera to Marker". I do this for every camera I have in the scene.
You can move the marker after you have set it.

Oh, ok! I thought that I might have misread it. I unfortunately don't have an answer to that scenario.
But it seems interesting. I might try to look around and see if I find anything about it.

Basically, you go to Scene properties and activate Stereoscopy. There should be an option for multi-view.
Add cameras in the menu and give them a suffix, then add the suffix to the cameras.
To render an animation like this, you might have to render as PNG.
EDIT 2: I also found this addon that seems to have support for animations: https://extensions.blender.org/add-ons/multiple-camera-render/
