This question was posted 8 years ago and still no movement on this idea.
Our CSM’s are managing a large book of business and we have many automations creating CTA’s. There is no way to mass edit/update the due date in bulk and it is extremely time consuming for each CSM to edit them individually one by one. And to update the dates of the tasks attached or playbook actions would necessary too. There has to be some bulk actions that can be performed to do these simple features.
