I am creating a roll out plan for a product, I have chosen the business project type as this seems better than the dev and software types. My only problem is that I want more categorising in the tasks menu. There only seems to be two levels of hierarchy in the timeline - tasks & sub tasks. I want more than this.
I have tried using epics but this does not work, they are definitely better in software projects.
Any ideas? Can I create a new task type at all, and configure the way it collapses and expands and holds tasks and sub tasks within it?
