Calculate geometry dialog - add ability to calculate x, y using any coordinate system

[BrianOevermann]

When using the Calculate Geometry dialog in ArcMap to calculate x or y coordinates for points, the only options available are to either use the coordinate system of the data source or the coordinate system of the data frame.

Many local governments use their relevant State Plane Coordinate System for their data.  However, when sharing data we often are requested to have the coordinates expressed in longitude/latitude.  In order to accomplish this, we must re-project the data and then calculate the x, y coordinates for the re-projected data. 

I would like to see an additional option added to the dialog--"Project into:" and allow the user to browse for the coordinate system of their choice.

Given that the x, y fields that are being calculated are not updated automatically, I should be able to decide what coordinate system should be used regardless of the data source or data frame.

Thanks for the Idea!

In ArcGIS Pro, the Calculate Geometry Attributes geoprocessing tool allows users to do just this!  By selecting the coordinate system you would like to project into (in red below), users are able to define new fields with calculated XY coordinates in any Coordinate System.
