I'm looking for a way to pre-set new custom publish dates on already published blog posts. In other words, this is what I want to do: 1. Select a live blog post. 2. Modify the publish date to a specific date/time in the future. 3. The post remains Published with the original publish date until the future date/time. 4. On the future date/time, the post's publish date updates and the post goes to the front of the loop. The most important is #3 above.
