Ability to create and update Tax Registration details against Supplier and Sites via API or interface

Hi Folks,

Is there a Public APIs available to update Tax Registrations at the supplier site level?

I know there is the table pos_party_tax_reg_int and import program Integrated Supplier Import Program which works for registration at the supplier level, however we'd like to be able to so this at the supplier site level as well.

We have found that we can populate the interface tables, create a batch, and submit the concurrent request.   Using this method, we can Create Tax registrations at Supplier and Site Level.
