Modify Slack Notifications based on PD schedule

I’d love to have PD’s Slack App update my Slack notification settings when I’m oncall. We use PD to manage our customer support rotation. When I’m on CS I want to get notifications for all message from some channels that I don’t otherwise.

Every time I go oncall I have to think through all of the different channels to remember to modify the notification settings. If I don’t then I can leave customers hanging, which is not good. Then, when I’m no longer oncall I have to flip them back. Of course, identifying the channels to update when I go offcall (?) is easier because I’m getting notifications for EVERY.SINGLE.MESSAGE.
