Creating Vendor PO and Invoice - VAT

Creating a Vendor [P.O.] on the system with Multiple Company setup and Assigning the Vat on the First company as show on the Picture

Upon Creating a vendor [Invoice], again it will go back to the percentage of the vat (5%) without the company it was assigned during the creation of [P.O.]

So I have to go back and Edit the Invoice

Any Fixed to this to make it Automatic?

Thank you and Thanks to the programmer
