Quick question about parallax backgrounds Options

[Barchetta3223]

I noticed that map settings event options are not included in rmvx. I was curious if there was a way to stop my parallax background from moving in a downward motion at a given point in my event. Whether through some event option I don't see or a script, I'd like either one. I'm currently working on an elevator scene that eventually comes to a stop (duh most elevators do ) So I wanted the scrolling background to stop when I tell it to. Can anyone help me?
