State Names are not Showing up in the LOV While Selecting "Ship from" as a Tax Determination Basis/R

I am trying to define a tax rule for GST but State Names are not Showing up in the LOV While Selecting "Ship from" as a Tax Determination Basis/Rule in Tax Rules Setup. As per Metalink Document, this has to be done manually in Trading Community Manager. IT

It looks weird to create so many values manually, Is there an alternate way to do this.
