Putting this item under review so we can investigate the scenario. Currently you can use Flow to automate posting. DRI/POC can be maintained in a list or file and message can be sent to Teams channels at designated intervals. For schedules as mentioned you might also consider using the Shifts app inside of Teams. This would provide additional features like shift swapping, activity lists for each shift etc.

Yes, Scheduled postings are very important in teaching. Particularly those of us doing Hybrid Teaching where 1/2 the class is in front of us and 1/2 the class is home. Being able to schedule the posts of links, stream video etc, will allow me focus on my Face to Face kids while they are here.
