Better link with survey
Currently : use id of response to link with extra survey. But when a survey is activated and DB are keep on again : is of response are updated. This can be a great improvment to use a uniqueid.
a new column uniqid can be added easily automatically(else need to create a question)
Review if new column are/can be exported in json, csv, xls(else : need question in extra survey)
- Allow usage of automatically set uniqID for question inside survey (by code/title)
