This would be a great addition.
I know that there is Velo code to have this scheduled to happen at set times - https://www.youtube.com/watch?v=KQnK3Nx8OSw&list=PL0y_aclKYoYhzHA9TbgEhzU68bvRI15mI&index=6
But for those clients that need the information to clear at a set time, this feature would be great.
I also love the idea of being able to schedule the publishing of a new page. That would be a pretty neat feature
