Scheduled Reminders about unconfirmed Stacks

Similar to GitHub scheduled reminders, I would like to get reminded every day at a certain time about all my unconfirmed stacks, like “Hey, you have 13 unconfirmed stacks: (list of stacks).”

Ideally, I would be able to configure
- the channel this gets posted on
- a search query or space from which to list those stacks (generally, I care about stacks owned by my team, not the whole account)
- the schedule (maybe cron) this gets posted on
- types of stacks to include (unconfirmed, failed, drifted, etc.)

I would like to be able to configure an arbitrary number of such scheduled reminders (different sets of stack, different channels, different configs, etc.).

Maybe this should integrate with saved shared views of the stack list, and just let me do a scheduled reminder for an arbitrary shared view (which will post the reminder whenever there’s at least 1 stack visible in the view) - this would be very flexible then, easy to use, and integrate well with existing functionality.

Maybe this could similarly integrate with Notification policies. Instead of posting directly to slack, it would just trigger my notification policy with the list of stacks, and I would format the message myself.
