Looking for a plugin to set post date without scheduling

Hey all,

I'm working in on a multi-author magazine site, with a simple problem: I want to set the date/time a post will publish, but keep it in Draft. That is, I want to separate scheduling from publication.

Here's the idea: I want to use Editorial Calendar to plan (among several editors) when articles will go out, without necessarily committing them to publish.

Any ideas? Thanks, community!
