No matter what way, you can only use one crowd file so I can only create one version and not both.
Ok. I think this is something between .dat crowdplacement files & .lua files. EA stadiums from Bundesliga & La Liga have neutral configurations in FIFA16 Tournament Mode, even though they are not default stadiums. So if I play Group E match against Spain, there are 2 big ultras groups in San Mames - different from default home/away crowds.
