As a project scheduler, I would like to exclude certain tasks from the critical path calculation so I can set milestone dependencies but still see the critical path for my tasks.

Currently, if I have a milestone like "Current Contract Ends" and I set a negative-time dependency on an earlier milestone like "Start New Contract Acquisition Deadline", that becomes the critical path in my schedule, and I don't get critical path highlighting in the rest of my schedule.  I would like to exclude the "Current Contract Ends" task/milestone from the critical path calculation.  

Thanks for considering this feature.
