subtask share the same key as parent

[Matthew]

It would be nice if subtask keys mirrored the parent key. Eg) Parent key Task-1, each subtask would be Task-1.1, Task-1.2....Task-5, Task-5.1

Looks much cleaner and intuitive from a user perspective.  I can look at this and see I have 5 main task with 2 subtask in each.  I don't need to look up a parent field or inspect each subtask to understand were they belong.
