Setting up four monitors on a Linux laptop via script

Although KDE discovers the three external monitors and the built-in display perfectly, I need this alias sometimes because the thunderbolt doc gets confused when I change the laptop attached to it: 

#:~> alias monitors
alias monitors=’xrandr –output eDP –output DisplayPort-1 –output DisplayPort-2 –off –output DisplayPort-3 –off –output HDMA-A-0 –off; xrandr –output DisplayPort-3 –mode 1920×1080 –output DisplayPort-1 –primary –mode 1920×1080 –right-of DisplayPort-3 –output HDMI-A-0 –mode 1920×1080 –right-of DisplayPort-1 –output eDP –mode 1920×1080 –below HDMI-A-0′

(Yes, it’s an L-shaped Setup on my desktop)
