How to make possible to inherit Citizenship, Mailing Address and Place of Birth from ORC to Core HR?

Hi team,

I'm getting a deep dive on the possibility to inherit Citizenship, Mailing Address and Place of Birth from ORC to Core HR.
Is it possible, in any way, to move the information populated in a Person Extensible Flexfield to the "twin field" in Core HR?
We need to ask to the External Candidate:
- Citizenship
- Place of Birth
- Mailing Address
that are not standard fields for Oracle Recruiting Cloud.
Do we have any workaround to do it?

Thanks in advance
Tommaso
