props

I'm adding working windows to my van here so it has a vertical offset; the only issue with just an offset would be that it would be visible on the inside, so it'll have to be rotated 10 degrees as it goes down here are the placement lines below: 255, 254, 256, 0.535596508244, 0.789351081531...

I read the docs and didn't get any clear explanation about this specific matter but is there any way to have one N/B Prop have a minor delay before it activates while being the same keybind for another prop? I understand thats probably confusing but I uploaded this video so you get what I mean.
