OpenURL to open the invoice->send email page

OpenURL to open the invoice->send email page

Hello,

I'd like to use a custom button to run a custom function to run openURL, to open the invoice->send email page.
I'd then like to preselect the "from" email address (from one of many i.e. it should be the logged in users address!!), add a bcc address and automatically choose the email template.

Is it possible to pass variables to the send email page? Any ideas most welcome.

e.g. https://books.zoho.com/app#/invoices/<zoho invoice id>/email

Thanks
