Mass Mail - but create drafts only?

There are a number of times when I want to send a mass email to a group of people, but need to edit them more than eM Client’s variables can handle.

Also, I’d love to be able to do more of a dry run to make sure I’ve setup my template correctly.

Is there a way I can get eM Client’s Mass Mail feature to process a message but only create draft emails?

At that point, I could tweak them all, and ensure I’ve emailed everyone, or delete the drafts & send again if I’ve got it right… or whatever.

I don’t know if eM Client can do that now, but it’d be a great feature IMO.
