How to Avoid Copy Receivable Invoice Tax Rate to Intercompany Payables Invoice

A customer has one operating unit per country (in this case Spain) but multiple Legal Entities. For taxes calculation, they must create X tax rates per legal entity exists (because the segment 1 of COA is the legal entity).

According to AGIS functionality, if both companies share the same Regime, the AR tax rate will be the same in AR and AP but I want to avoid that because then the segment 1 for the tax account will be different.

Is there any way to avoid this?

I already tried updating the AP interface but the AR code pastes anyway and also try the steps in Doc ID 2393240.1 but it doesn't work.
