How to Default the Tax Deduction Account Number in the Invoice Header Additional Information

When creating an invoice, we need to go to the additional information section and select the context as "India" and choose the Tax Deduction Account Number from the list of values (LOV). Since we only have one Tax Deduction Account Number, is there a way to set it as the default to streamline the process and avoid manual selection each time?

We've explored many community posts, but none clearly address this issue. We've also tried several methods without success. If there is any workaround to default this Tax Deduction Account Number, your guidance would be greatly appreciated.
