I'd like to add a custom field to the "core" demographics fieldgroup: the place of birth. I created a custom field, but I can't figure out, how to put it into demographics fieldgroup. Is it possible to do somehow?
Thanks.
You may find this new feature could deliver what you need - the MIH is still open and nearly fully funded iirc

You can use JS to move custom field from custom group accordian to demographics accordian.
