@mikecote Should this be a case feature or are we planning on doing this in the rule details page?

[mikecote]

@ymao1, this is still a grey area. Some PMs don't want cases as the only way to assign/acknowledge alert instances, which may require something like this. We can always close the issue until we have clear requirements as we don't have any today.

Closing due to no defined requirements.
