Auto calculating/ auto adjusting dates for tasks in Portfolio

[Braidon Waggoner]

We are using Jira Core + Portfolio for general business project management and are looking for a way to auto adjust subsequent tasks (and sub-task) when a preceding task's start and end date are adjusted. Right now when a task is completed (or delayed) every follow-on task has to be manually updated to reflect the revised date of the precursor task, we would like this to be auto adjusting, IE- if a task is completed 2 days early then all follow-on tasks slide back 2 days.
