Hi Rachel - yes, you can do this. Someone else may have a more eloquent solution, but here's how I would do it for now.... You would need to Insert Formula Column and create there. You would probably need to add a few in this case. One, to calculate the sum, one to calculate the percentage of the sum, and then another to add the flag if the percentage of the sum is >90%. If you have a Time element listed in the Columns section of the Ad Hoc Component Configuration area, you will need to remove that first because otherwise, the Insert Formula Column option will be grayed out. After you add in your formula columns, you can add it back.
