You may give the user group with “Survey User” access right level. In your sheet, create a “Select User” field with assign feature. Then, filter out entries with “X” in the “Y” field and use mass update to update the “Select User” field to that specific user.
Thanks but we are looking for something dynamic and less manual.
Something like the variable $USER_Dept where Dept is a field in the users table, full or external users.
