I want three tasks to be due the week before the project. 10 tasks are due a month before. 12 tasks are due 2 months before, etc. etc. All based on the completion date of the project...not the start date.
Every project has a different length depending on when they start and need to end, but they ALL have things that need to be completed at certain times.
It doesn't really matter to me when I start, some weddings we plan in 6 months some in 16 months. But they all have certain milestones we need to hit (invites at 10 weeks), things like that. All based on when the actual project "due date" aka wedding date is
