Insured | Social Security Number vs Tax Identification Number

With the December 2022 iPipeline release, the insured will have the option to enter a Social Security Number or an Tax Identification Number for MNL and NA.

Do we need a separate field within FAST for a Tax Identification Number?

Or have the TAX ID go to SSN field and then have the Government ID Type field show a separate option for example Tax Payor Identification Number?

Should this new field be added to the Party Matching chart as a weight?
