Do level1techs KVMs allow 2+ active pc's?

Just what the title says. Say, hypothetically, I am slowly becoming kinda the computer guy in my lab, and sometimes people bring me their computers for software help. I have 2 monitors and 3 (min) computers at my desk. The KVMs will allow me to quickly switch between them, but will they allow me to route one computer to one monitor, and another computer to another monitor, and I just have some toggle for my keyboard and mouse?

Or is this not a feature on these KVMs and I’d have to go with some single monitor KVM (x2) setup?

Thanks!

PS. I haven’t found one, but if there is a manual for these, that would be awesome.
