Thank you for your response I appreciate it. I am trying to have a nested object for regularPrice, and inside the object should be any property (eg. AUD, NZD, USD etc.) that has a float value so when returned on the document it should have something like this

{
  // other properties
  "regularPrice": {
    "AUD": 20.20,
    "NZD": 20.00,
    "USD": 12.00,
  }
}
