Yes and yes. You can import social posts from a CSV file to any of your connected social channels, by going to Content and clicking “Import Content”, which is located on the right-hand side below the content creation box. Lately will help you to match your columns to our database fields, see a preview of each post before you import, and then import directly to your Content Pipeline for easy scheduling.
In addition, you can optimize content from your blog (and blogs you like and follow) by adding their RSS Feeds to Lately. We'll import posts from any of your selected feeds, and then you can either choose to auto-publish new content or send it to your draft folder for editing and scheduling at your own pace.
