I want to be able to organize subtasks within an overall task.

I'm currently adding subtasks to an overall task in the order I want to check them off. However, after I've added a few subtasks, I find I might want to re-order them and/or insert one or more higher or lower in the list of subtasks.

I'm hoping this is possible. Otherwise, I need to re-enter the entire task in the "new" order. And, if I add another subtask and can't insert in the latest order of events, I'll need to start over again.

Thank you for your assistance!
