I dont see an option in the config to change it from scrap to economics

"Purchase Prices": {
  "scrap": { //item short name
    "amount": 1000,
    "displayName": "Scrap"
  },
  "Economics": { //use Economics
    "amount": 1000,
    "displayName": "Money"
  },
  "ServerRewards": { //use ServerRewards
    "amount": 1000,
    "displayName": "RP"
  },
 }
