Copy and past report, update links

I created a new report within my current ReportProject in VS 2005. I copied and pasted my tables, lables, etc. into this new report. I then recreated the same datasets as the other report except to name them different.

All my fields though in my table object are still referencing Fields!. I think I need to change it to reference the new dataset name but having to go through the expression of every darn field to do so. How can I tell all my fields to use the new datasets I have 3 datasets. Is there a mapping tool that I am not aware of in SSRS 2005 and VS
