Customize ALL Zoho Sign notifications

Zoho Sign allows to use Organization's email address and gives ability to customize SOME email templates, such as Sign a document.
However, there are a number of notifications that can't be customized (recall, has been signed, reminder, etc).
Similarly, SOME of these notifications still send from notifications@zohosign.com

A ticket has already been created and no good outcome out of it.  Trying to create this as an idea others can vote on.
