Capture start simultaneously on more than one Iphone?

Hi. I’m working on a project using Metahumans and Metahuman animator and we have 2 iPhone for facial animation. I already know that I can start capture from the Capture Manager, but it only allows me to start one at a time. Is there a way to start both with one click?

If you want to start multiple devices you should check out Unreals Switchboard.
