How to change Non-Recovery Tax code combinations which defaulted from Tax Expense from Tax Rate leve

Hi Team,

Good Evening and Good Day

We are using R12.1.3 version and currently all Non-Recoverable Tax code combinations which defaulted from Tax rate from Tax Expense Account.

At Tax Rate level we have mentioned has Cost Center Segment value (one of COA segment) as Finance, so every time when Non-Recoverable Tax calculates by system - system takes code combinations from Tax Expense account i.e Finance as cost center

My requirement Is - Instead of picking Finance as cost center which was mapped in Tax Expense account in Tax Rate - Only Cost Center should pick from Invoice distribution and remaining combinations from Tax Expense Account. - Is this possible by doing SLA customization? if it is possible - Can we see non-recoverable tax code combination changes during tax calculation time at Invoices?
