Process Design tools

For whatever reason, I don't know why I am jaded with software when it comes to planning tools, especially for easy-to-use dynamic scheduling. Why there doesn't exist a scheduler that quickly lets me pull down a list of team names, lay out a short term workplan, and then automatically propogate their tasklists or calendars is such a void in my head - long term MS Project schedules are great, but 3 week lookaheads are essential as well, especially without spending nights doing excel worplans?
