Please add the ability to easily change the currency when creating a Sales Invoice.

With France's new mandatory e-invoicing requirements coming into effect, many businesses invoice clients worldwide in different currencies (USD, GBP, CHF, etc.). The current process is not intuitive. It would be extremely helpful to have a simple currency selector on the Sales Invoice screen that allows users to choose the invoice currency while keeping their accounting base currency unchanged.
This would make Dext a much stronger solution for international businesses operating from France.
