I've looked through every section of the Tapo app and I can't find any way to create a shortcut to do this.  My cams are all C120s and C225s but none of them show a Reboot option in the actions I can assign to a shortcut.  

I hope I'm missing something here because it's a pain rebooting 9 cameras one by one.  

Why would I want to do this?  My home network is a mesh system and sometimes the cameras connect to a mesh unit that doesn't have the best signal strength for it.  I've found that rebooting the camera fixes this 95% of the time and I'm thinking that instead of going one by one through each camera, it would be easier just to reboot them all with one shortcut.
