Set project start date and auto assign due dates

Based on being able to set how many days from start date - eg 0 + 3 days etc

The only way I can think this would work is through importing templates. As you know spreadsheet software is very powerful in date math and you could create a template with a project start date and define you math. I think the interesting thing would be to be able to put in the number of days not counting weekend. Maybe I can find an Excel formula for that.
