Feature Request: Problem Public Comments filter down to incident tickets

I understand that only the first time the problem ticket is solved that a public reply will filter down to the incident tickets, but we would like all public replies to filter down. We often have problem tickets with 100's of incident tickets linked. We then have to update all of the incident tickets in batches of 100. I'm sure there's situations where you wouldn't want a public reply on a problem ticket to be shared with the incident tickets, but it doesn't apply in our business model.
