I realize this might be more a Project Management add, but is there a way to add another level into RTM? I work about 24 accounts. I would like to create a list for each one. Then a second level of tasks, as I might have multiple projects going on for each task ...and I need to track the progress for each.

As an example. I have to create 4 reports for one of these clients. I created the list with the client name. I have created 4 tasks ...one for each report. However, I now have no way to track the steps for each report. There might be an additional 5-10 tasks as part of this report creation.

1) List item.
1a) Task
1b) Steps (or a second level of tasks).
1c) Notes
