so my Q is: Currently i have only 1 default currency per client, while i need several billing currencies for its orders (Choose the order currency at the 'New Order' tab instead of choosing a default currency at the client's profile)
Is there any way to do it without getting in the code and making a new template for it? (some module addon for example). If not, is there any specific tutorial on how should i a custom field and connect its chosen data to the invoice and change it accordingly?
Any help will be highly appreciated!
