Scheduling a task on the Nth business day of a month

I'm wondering if anyone has found a way to schedule a task to occur on the Nth business day following completion of a predecessor task. For example, I have a marketing project plan and I have to produce a report on the 10th business day following completion of the "Campaign Launch" task. I can manually schedule the report but if the launch date moves, then I have to go back and manually reset the date of the report. 

Another example would be scheduling a task to start the first business day of the month following completion of the predecessor task.
