I would like to show the gannt chart information on a single line. Let me better explain.

Consider a project with three phases and milestones between the phase. Phase 1: Investigation followed by milestone - POR Followed by Phase 2: Development followed by milestone - Release. Followed by Phase 3: Shipments followed by milestone - EOL.

I'd like to create these phases using the task duration, start date end date features in Project but report out these tasks and milestones on a single line (collapsing the 'task' details). With different colors for each phase and milestone.

Is this possible in Project?
