Expression field in view using AGOL UI

It sounds like we can add calculated expression fields to “advanced views” in AGOL via the Admin REST API. The view would be uneditable.

Add to Definition (Feature Service)

"sourceLayerFields": [
  {
    "name": "zipcode",
    "source": "zipcode"
  },
  {
    "name": "salesavg",
    "alias": "SaleAveragePerCustomer",
    "expression": "(Total_Sales_FY13 + Total_Sales_FY14) / Customers",
    "type": "esriFieldTypeDouble"
  }
]

(It also looks like there's some GROUP BY / aggregation functionality in some of the JSON examples too.)

This idea is to create an expression field in a view using the UI, instead of using the Admin REST API, which isn’t user friendly for non-developers.
