How to have a task mirror the length of a task group?
 

I have a big list of tasks that lasts for say a year, but will change as I change the tasks. I have another task, call it project management, that needs to start when the big list of tasks starts, and end when it ends.

I want one management task that lasts as long as the total of the work tasks, and I don't want to have to manually update it as the work tasks change during planning.

1) Is this a reasonable thing to do? Or is there a better way to organize things?
2) If it's reasonable, how do I do it?

Thank you.

Unless I am mistaken, that sounds like OmniPlan 2.0’s "hammock" task feature.
