4k Laptop Scaling reverts to 125% when the external monitor is unplugged

I have a 4k external monitor which I use at 150% scaling. My laptop’s internal monitor is also 4k and I typically use it with 200% scaling. If the external monitor is unplugged the scaling for the internal monitor will switch to 125% from the 200% that I have set. I then have to go into settings and fix it.
How can I make my preference stick?
