Hi there, @corryca ...
Not sure. I don't know if you monitor the monthly Canvas Release Notes, but the latest publication of Canvas Release Notes (2022-10-15) - Instructure Community (canvaslms.com) indicates that "Pages" (not "Assignments") will allow us to schedule a date/time to publish content pages. So, while I certainly cannot speak for Instructure, maybe this is a sign of things to come for other parts of Canvas? Purely speculation on my part...for what it's worth.
