Linking Planner Tasks to Update Timeline When A Single Due Date is Changed

Hello, 

I'm testing out Teams/Planner for a program launch/maintenance. We are using Planner to manage our checklist of items that must occur before/during/after the launch. 

It would be ideal if the tasks could be linked somehow; so when a due date for one item is extended, the other tasks are updated accordingly. It would be even more ideal if we could apply this sort of roll-over to a specific bucket or group of tasks. (Some items cannot change, so we would want to exclude those from any auto-updates)

I'm having trouble finding out if this is possible, but my first impression is that it isn't. Any guidance is greatly appreciated. Thanks for taking the time!
