Updating civic information - state senate, state house, us congress

I have been trying to update these fields from an external source. These values are in the address object of the party object as LocalGovermentDistrict1, LocalGovermentDistrict2, and NationalGovernmentDistrict. In CsContact they are StateSenate, StateHouse, USCongress.

It looks like in the Party object if you POST it updates the address but not the CsContact Object

If you PATCH it does not work.

If you PUT it will update the address but not the CsContact Object.

Is the only solution to update CsContact to PUT the StateSenate, StateHouse, USCongress (patch doesn't work)? Is it ok to work directly with the business objects and not use the party object? Is there a way to update both through one call?

Right now, it looks like we need to make a PUT to the party object and a PUT to the CsContact object to update in both places.

Yes the address we are updating has the address purpose setup to set the Congressional Districts.
