save multiple drafts at a time in Robo-mailer

I'd like to save multiple email drafts at a time in robo-mailer NOT templates of emails, multiple drafts at a time. For example if I am in the middle of an email for recital kids/ competition kids and/or adult students (etc. )and an emergency comes up (emergency closure due to weather, illness/teacher calls off, need to cancel a class, etc) I need to be able to save one draft, quickly type and send another email, and then jump back to my original email without having to open an entire separate app or window to copy and paste where I was at in the previous email - or god forbid the page refreshes or my internet goes out and I lose my draft. Also, saving drafts WITH attachments too.

TL;DR Robo-mailer has multiple draft options for saving, including attachments.
