Question about insta 360 go 3s

Context: Planning to buy a go 3s this weekend but the 30mins battery life at 4k seems a bit short for me, I know that theres a standalone go 3s so I have an idea but would like to confirm.

Here's the idea, buy the bundle pack + a standalone camera. So I have 2x go 3s and 1 action pod.

Scenario: Pair both cam to action pod. Let's name it Cam A and B.

A into pod, remove it for recording, B go straight to pod for standby and charging.

After 30mins A is depleted and will be charging in the pod, B will go as the shooter. Vice versa, until action pod and cams are all depleted (could go forever if I have a large battery pack).

Question: Is there a way to select which camera preview in the action pod? I'm asking coz I want to make sure that the framing is right in the current shooter.

Or is there a better solution that I'm missing?
