Hi @carllwyman
Unfortunately, I am afraid that is currently not the case because of how ACF saved the field values.
ACF saves the field values as post/user meta records. By setting the fields default value, this will auto load the value when editing the user records however, this does not update the records’ meta value.
As an approach, you would need to loop through updating the values using the update_field method.
Hope this helps.
