Allow additional fields to be required using ArcGIS Online

[JoshWhite]

Currently, the design for ArcGIS Online and Collector is for nullable fields to be not required and non-nullable fields as required.  I would like the ability to require fields that are nullable as well at my discretion rather than having to adjust this on the back end of the feature layer.

It is very uncomfortable for casual ArcGIS Online users to change fields setting in ArcGIS for Desktop every time they need a field to be required. It should be as easy as selecting a field in a feature layer settings in ArcGIS Online.
