Foreign Currency Invoices to have converted functional tax amount as on Supplier Invoice

Hello All,

I have a question regarding foreign currency invoices in Oracle fusion.

The supplier invoices show a GBP VAT value as well as EUR VAT value. The invoice is being entered in EUR on the system as the supplier needs to be paid in EUR. This is the foreign currency invoice where GBP is the functional currency & EUR is the payment as well as invoice currency.
User needs to be able to enter in Fusion AP Invoice interface the GBP VAT value present on the supplier invoice.
This GBP amount is what they need to use for their VAT return (not the system converted amount). It is fine if the system still needs to do its own currency conversion (as there might be other parts of the business that need this information), as long as there is a way of capturing the GBP VAT amount on the fusion invoice interface. Additionally, an extra column in Financial Tax Register is required for these GBP entered values.
