Thanks for posting.
My understanding is that you want:
- ability to add project milestones to project group milestones
- ability to add project group milestones into a global milestone.
- ability to add project tasks to a project group milestone directly
- ability to add a task to a global milestone directly.

For me it would be better when I create to-do's I can add them to milestone and on dashboard in a widget, I could see milestones with percent progress and if I expand them I could see the to-do's what I added to milestone.
