zimbra is really nice..but there is one feature that I really find very important and I dont understand why its not implemented. Its following simple use case - manager wants to assign task to someone.

I've searched forum and found one way how to do it:
- all people that want to get tasks from manager, will share their task list with this guy
- manager can add tasks to their task lists

There's enchantment for this feature in bugzilla from 3 years ago :
Bug 15832 – Tasks: Need ability to assign tasks to someone else

We are just starting to use zimbra..so I would like to see how others are solving this use case.

Is mentioned solution the best one? I mean..its not bad way..its just implemented feature would be more comfortable and easy to use.
