MarketPress: Currency format, decimal and thousands separators

Hi, it's my first post here since I joined wpmudev.org last week. I'm starting the translation and localization of MarketPress to Brazilian Portuguese and I noticed that is not possible to change the currency format. Brazilian Currency (BRL) was supposed to be written like this R$ 1.000,00, so I need to know how to change the separators to meet our local standards.

Greetings, and congratulations for the great piece of work we have here.
