Hello!
I have an automation that creates task and subtask in a Epic with set start date an due date using this formulas:
start date: {{createdIssue.Due date}}
due date: {{Start Date.plusDays(X)}}
So if a epic is transitioned then is create a set of task with "waterfall" dates like this:

But sometimes we need to change the start date of a task, i want to be able to update the due date and start date of the following task with automation
