Is there a way in Suppliers to show the currecy code instead of the currency name?

 Greetings,

Is there a way:

1) In the Suppliers page to have the currency code (USD) instead of the currency name (US Dollar) show in the Invoice Currency field.

2) In the Create Bank Account page Bank Account region to have the currency code (USD) instead of the currency name (US Dollar) show in the Currency field. 

Thanks,

Kelly
