Hello,
the User Profile Review allows individual attributes to be reviewed. Unfortunately, there is no option to define your own validation to restrict the possible values.
We noticed a problem if you want to recertify a date, as the reviewer can enter any date and this is of course not desired.
A similar problem would occur if you wanted to check attributes such as a telephone number or email address, as this is unfortunately not possible without a meaningful syntax check.
It would be very practical to define a separate validation for each attribute in the review.
