Is there a way to control the default filename for images taken in the survey123 app?
for example I want field1 value + the date value
(both are questions in the form).
It seems to currently be set to "images-YYYY/MM/DD-random numbers.jpg"
No this is not possible, but you can rename the file before submitting the survey through the field app UI.
Just click on the default file name and write in the name you want.
