[FTC]: What is allowed in the driver station?

[Nstarr445]

Hey everyone! Over the weekend our ftc teams participated in our first qualifier of the year. As the drive team coach, something that I noticed is that it can sometimes be difficult to see the field from the drivers station, especially if you are a relatively short person. So my question is, would it be legal for drive team coaches to bring a short stool or crate of some sort into the drivers station, which one could stand on to help get a clearer view of the field? Thanks a lot, and good luck to everyone who is competing in the next few months.
