After reviewing what you wanted to do, spoke to developer, I may have misunderstood you if it isnt the locations you want private but the actual SEO Pages. You can accomplish much of that within the admin section under WP Pages, there should be a filter to mark all the Store Pages you select to private. SEO Pages follows the WP rules. There is also a scheduler in WP admin but I believe they do not have a publish all on a select date. You would probably have to click on each page and add the schedule, but as noted there may be a plugin that can handle bulk WP Cron for pages.
I hope I am understanding the question and provided you with a clearer answer, we can revisit this if it is something the developer can do as a customization at a later date. he is currently coding and troubleshooting this week,
