Stacked gantt visualization

[Pinellas-Jason]

It would be great if there was a way to stack numerous start and finish dates for tasks in a gantt chart?  Our CIP project managers enter an "Estimated", "Scheduled", and "Actual" start and finish dates for each task in our project management software.  Depending on vendor delays, weather delays, etc., these dates can change often.  I'd like to be able to visually show these "sliding" date frames in a gantt chart. Preferably stacked in different colors.
