Okay, I’m going to make this ask as simple as possible:
Give us the ability to define a new Airtable formula function called UUID()
The output of UUID() remains STATIC and anchored solely to the RECORD_ID() value.
This means the ONLY time UUID() values change IF and ONLY IF the RECORD_ID() value changes.
As a byproduct of this, whenever you duplicate a given record/row, that duplicated record/row’s UUID WILL BE DIFFERENT than the source/original record/row.
