Zoho Invoice - snail mail template issue

I've created a good looking custom invoice template.
When I want to sent it by snail mail, zoho invoice shows me a preview of the envelope.
On this envelope I can click to preview my invoice that will be physically send by mail.

problem => the template that now is used for snail mail is different than my own template.
All the info is there, just in another template.

What can I do to secure that my invoice looks the same for both e-mail and snail mail?

kind regards,
Doron
