ATEM Mini Pro ISO Multiview - Customizable?

Hello and thanks for any help.....

I'm rigging up an old ATEM Mini Pro ISO for a small portable setup and Would like to customize the multiview as I have with the Extreme models. Updated the firmware.

Is this configurable now? Has there been a software or firmware update that allows this?

Thanks again

Billy

In my opinion this has always worked? I’ve had an Atem Mini Pro Iso and I could customize the multiview.
