[SmartCrawl Pro] Custom Post Types Not Showing in Sitemaps

My website uses custom post types for real estate properties that are for sale. I just ran the SmartCrawl Pro, and it doesn’t appear to be including any of those by default. I was given the opportunity to add them manually, but in the future, when new properties get added to my site will the new URL’s get automatically added to the sitemap, or will I have to manually go in and add each one? Also, when I change the post to “private”, will SmartCrawl Pro automatically remove it from the sitemap?
