Enable sorting in Fields generated from Arcade Expression in Pop-Ups

[MoritzGumz]

When using AGOL or Portal for ArcGIS and creating Arcade expressions in Pop-Ups, the field [temporarily] shows up in the attribute table. 

Other than seeing the field in the attribute table, there is nothing more that can be done with the field.

Being able to sort the field or get statistics would be very helpful!

Be aware that this will require a full table scan and apply the expression to each record. This might be a operation which can take a long time. In case the data is rather static it would be better to add the field and apply the expression in the field calculator in ArcGIS Online. This way you will be able to sort without applying the expression to each record.
