Drafts that don't go out

I want to use typefully as our home for planning all tweets. Right now unfortunately, if I schedule a draft but don't finalize it before the scheduled time, the half-baked tweet will go out (I think?). So I have to keep a separate calendar and jump back and forth to typefully. Would be great to just have a checkbox that determines whether the draft is ready to go out or not at the given time.
