Append to Draft

I often create emails from different sources and it would be good to be able to compose an email without saving everything to disk.
I.e. I get a request from a customer in an email I send this email out to my colleagues with different tasks and get a response back from each of them. In text and attachments.

When I later will compose my response to the customer I need to save all attachments out to disk and later back into the email again.   It would be productive if this operation could be done altogether inside of Verse and not the need for save to disk.
I.e open draft email in a new window and drag attachments from one email to another, drag recipients from one email to another.
