Multi Currency for WooCommerce – Decimal separator per currency

Hi,

We are currently using the free version of Multi Currency for WooCommerce.
This works perfect for us, but now we run into the following problem:

The default currency for my store is Euro, which uses a comma for the decimal separator (and a dot for thousands). But we also sell in the United States with dollars, where they use a dot for the decimal separator.

How can I configure the separator to show a different separator per currency?
