Possibility to select specific articles or even ALL articles from our wordpress site for example, and in the Autopilot feature, have enabled an option to write a single new section (h2+paragraph) in the bottom of each article (obviously related with the article subject), every pre-selected period of time (every day/week/month), and after it's done, update the published date to the "today" date. This way, besides the possibility to add new content in Autopilot, it will also refresh existing content every given period, automatically. An additional feature that might be harder, but would also blend well with this, is that with the new section created for the article to also include internal linking to other pages.
