Saving drafts in bulk mail

[ClubCuddly]

Just wondering if this is potential future option. Having the ability to save a draft and returning later to modify, discard or send would be nice. 

Currently I am writing my bulk mail messages in notes (mobile) and then trying to format within the bulk mail editor. But other administrators/moderators don't have access to make changes to the message I am formulating. 

Hope I'm making sense.
