Dual card slots on a7s-iii - any way to auto-switch in video mode?

[getitinwriting]

New owner of an a7s-iii. There are several options for configuring the dual SD slots, but they're mostly for still shooting. I've been unable to find any documentation on whether it's possible to configure it so that, when shooting video, when card 1 is full, it starts writing to card 2. Can anyone shed light on whether this is even possible?

Dan, try config'g menu like below. When your issue is fixed, I have an a7Siii question for you.

Thanks, garuda. I'm pretty sure I had this set to On and it didn't work - stopped recording when #1 was full. That's why I assumed it was only applicable for still shooting. But I'm not going to swear it wasn't pilot error on my part, so I've confirmed it's set correctly now, and I'll report back after the next shoot whether it was me or the camera.
