Feature request: Allow planning by days following Authorization to Proceed or similar undefined start date. I realize this runs into its own problems but 99% of the time I don't know when that date might be yet I need to lay out a schedule to support a proposal to get the funding to do the job being planned. Weekends, holidays, and other specifics are less important than a view of task relationships and milestones over weeks and months.

Even the huge MS Project cannot or will not do that.
