Default invoice field value based on legal entity of the invoice

Summary:

We are implementing the Oracle solution related to withholding tax for India. By implementing this feature, Tax Deduction Account Number becomes a mandatory field on the invoice page. The requirement is to default the value on the field based on the legal entity that has been used for invoice creation.

We have 10 LEs which are going t use this feature. Is there any customization possible which can help us in defaulting the value- as it is a challenge for the users to come to the additional Information field every time and give the correct TAN.
