Tax Registration number Default on AR Invoice basis on ship from location

Summary:

Hi Team,

Below is the scenario

We have 1 LE with two branches in India, having different GST Registration numbers.  So we have created one Ledger, One LE with two Legal Reporting Units (1 per branch Chennai and Mumbai ) and one BU.   Each branch will raise the invoices and the expectation is that the tax registration number should be defaulted based on the Legal Reporting Unit when the invoice is interfaced from various sources like Project contracts, Order Management, SCFO.

We have setups Mumbai LRU as default so any invoices are interfacing is having default Tax Registration of Mumbai.

Can we create a Tax Rule to default the Tax Registration Number basis on ship from location so that if shipping location is Mumbai then mumbai tax registration should appear on AR Invoice and if shipping location is Chennai then tax registration of Chennai should appear on AR Invoices.
