It would be useful to have the ability to give a field a display name to replace the field name in the displayed system to staff

 in my case I capture multiple address information ie time at address in to "years" and "months" via drop down 

Example - current address would be "Years" - 1 , previous address would be "1_Years" - 1 

as you can see the use case works but is messy having the option to name the fields both "Years" but having a field ID  being unique would make the UX better for users.

As mentioned in a previous Idea this makes even more sense in a wizard .
