Is there a way to record multiple cameras at once in OBS?

Hello again. You guys were a ton of help last time I asked about recording using multiple cameras. I’m back with another question.

Currently we’re using Iriun to record to OBS using 4 different IPhones. But the way OBS sets it up is I have to put each camera in its own “scene” and then manually switch between cameras using hotkeys live during recording. This isn’t too difficult, but it would be so much easier to record all the cameras at once and then switch between them in post. Is there a way to do this?

Thanks in advance!
