ACC PS4 - Adding json files?

I have just rented a server for Assetto Corsa Competizione on PS4.

I see the Config Files section of the web interface and have been able to make basic changes, and the server is working.

However, I only see three json files in the Config Files section: seasonResult.json, event.json, settings.json

(I'm looking at the doc linked here: How do I host a console private server in Assetto Corsa Competizione? – 505 Games Support)

The docs I have suggest that there should be other json files too, like "eventRules.json" and "assistRules.json", which seem to be necessary.

Is there a way to add extra files?

The dashboard says that there is no FTP access for ACC PS4.

Thanks,

Dave

I spoke to someone on live chat and they confirmed that Nitrado only supports those three json files, which seems wrong from the docs I have as it limits what can be configured.
