Add "Draft" as an option to the "Audience" dropdown menu of blog posts

The old PI Square allowed users to save draft versions of blog posts, which were not visible to anyone other than the author. This allowed users to save changes to their blog post without publishing it. In the current PI Square, you must take great measures to hide your blog post until it is ready. My current strategy is: 1. Write the text portion in Notepad++. 2. Paste the text portion into a blog post set to be published far in the past (so that it will appear last in the list of blog posts) and with the audience set to "Customer" (most restrictive without losing access). Then, I save the blog post, which publishes it. 3. Add formatting, images, links, bulleted lists, and numbered lists, saving along the way and hoping that nobody encounters my unfinished blog post. This is too much. Please create a new "Draft" option for the "Audience" dropdown menu of blog posts. Blog posts with this audience should be visible only to the author.
