Change net colors

Anyone know how I'd go about changing net colors? Some teams have colored nets by default, Juventus does at least. I've looked through graphic.fmf but found no obvious solution to add a custom color to a specific ID. Theres a nets folder inside the pitch folder, but theres very little code in the xml and nothing that points to specific ID's. The net png's are all white/gray.

Help would be highly appreciated

En antiguas versiones del juego se podia hacer, pero creo que a partir del FM 2020 ya no.

I think its still possible. Theres a Nets folder in graphics.fmf with png's and xml.
