1 laptop using 2 monitors to 1 monitor and a PC using the other

I have a really odd situation, I have no idea how this can work. Essentially, I have a 2 monitor setup for work, but I would like 1 monitor to switch between the work laptop and my main PC. When I try to do an HDMI switcher both of the monitors either change inputs or everything moves to the 1 remaining monitor. Is there any way to just change the input of 1 monitor back and forth without it wrecking everything?
