Issue Adding New Task List Via API

Issue Adding New Task List Via API

One of the required parameters for a new task list is Milestone ID.  I can easily look up any existing milestone and pass its ID through the add task list method.  However, I want to create new task lists under the "None" milestone (default value when creating a new task list manually), but I cannot find a way to retrieve the associated Milestone ID for "None".  This can be found indirectly if you already have a task list with "None" as the related milestone, then return a list of task lists for the project and select the Milestone ID for that specific task list, but the ID is not the same per project and does not show up if you are creating a new project with new task lists.

Does anyone have a solution?

Thanks,
Steve
