Currently all milestones roll upward into higher levels V1 Project Tree roadmap views. This causes enterprise-level roadmap views to become cluttered with all the lower level milestones. Often, the lower level milestones are too granular to be relevant.

We need the ability to toggle the roll-up of milestones in order to turn them off. It would be nice if the milestones at the highest level of the V1 Project Tree selection could optionally remain on even if the roll-up milestones from lower levels of the V1 Project Tree are toggled off.
