Sending invoice pdf via email from Zoho Invoice

Sending invoice pdf via email from Zoho Invoice

Hi,

two questions:

- how can we remove " - Sent Using Zoho Invoice" from the subject line when sending out invoices directly from Zoho Invoice?

- can we add information from the contacts module when creating an invoice / to the invoice without having it show up on the actual invoice? This info is only required when sending out emails (invoice, reminders, etc.).

Thanks
