Select Individual Custom Fields for Export

It used to be in Constant Contact (Pre 10/01/2020) that you could select individual fields for export when exporting lists to .csv files.  However with the new "update" to the user interface, the individual custom fields can no longer be selected for export.  It's now replaced with one one box to export all of the custom fields.  

Why this was changed in the new user interface is beyond me.  Now when exporting all custom fields I have extra steps to perform, removing unnecessary columns, when reporting the data within our company's records.  

Please allow us to select individual custom fields for export again.  This feature was already in Constant Contact before, but now it's not.  That's not a good sign when an "update" takes away more than it adds.
