Tray liner dividers

[Black_VY]

Hi i hav a VY ute with a factory tray liner, on the sides of the liner it has some vertical slots where it looks like you could put some sort of divider in it, i've searched the web and the forums here and couldn't find anything, does anyone know if there is something you can get for it?
Cheers

Slots of wood work great, my mate has a crewman with the liner in it, he just throws a slab a wood in it
