How to personalize e-mail languages by customer?

We are serving customers with many languages. Would be very important to send each system e-mail with their own language?

As I understand, currently ZOHO Invoicing does not offer a possibility to store customer languages? And also only supports one language template at the time? I hope I am wrong and look forward to your comments and instructions.

In case I am not wrong, this small addition would make Zoho Invoicing much better :-)

1. Please add a custom LANGUAGE field to Customer details.
2. Please add a possibility to store multiple e-mail templates for each section: invoice, reminder, thank you etc. and allow to set the corresponding language they are saved in.
3. When sending e-mails, just simply match the custom language template for customer language if found from the system.

Thanks,

Niko
