Set/read network variable? (SetCustomProperties)

Hi, I am trying to set a custom variable (player gender). Then when a new player is detected I will read from this network variable and activate the correct player group in the prefab clone. Can I set/get a variable with SetCustomProperties ? any example?

void FixedUpdate()
{
if (photonView.isMine)
{ 
//do nothing
} else {
//if their position is 0,0,0, move them to where they should be then..
//read the gender from custom properties before activation
}
