De-Duplicating Surveys

We used date of birth to help clean the data and would like to do so again. Is there flexibility in the age/birth year question in HIFIS to add that detail?

The easiest way I see is to use the new INTERVIEWEE ID field to store this. This new field can be toggled on or off (event-wide) and opens up an extra field in the screening form where users can enter ‘some kind’ of identifier to help avoid duplicates. If you were to put the DoB there would that work?
