Want to Turn On Focus Mode On a Single Device, Not for All?

I used to use my "Do Not Disturb" mode on the computer and I did not turn this mode on on the phone so that I could see it on my phone when I received messages and calls. After this update, when I put any of my devices in do not disturb mode, they all started to switch to this mode. Is there a way to do this for a single device? This really makes everything hard for me.
