When I update a transaction in USD (foreign) currency, I input the CAD (Home currency) amount that was taken from the Credit card statement, and when I press tab to switch to the next field (CAD Tax amount), the CAD tax amount field should already update or show as a suggestion underneath the field with the proper exchange rate calculated from the CAD Total field update.

Right now the auto-update only executes when tax is set as fixed tax value and not as extracted amount value.
