Nets and corner posts colours

Hello.

 I would like to know if it is possible to change the colour of the nets? I remember that in an older version this was done.

And also the corner posts? Indeed, when I watch my game in 3D, they are white with a simple line in it... so "faded" compared to the rest...
I would have liked to know if it was possible to put them in the colours of the club or the competition. If anyone knows how to do it?

If ever a moderator could delete this message. Indeed, as far as I can see it works for corner posts. But in the club where I am, they have reversed the primary and secondary color...
