Question about creating a Request Set

Hi Gurus!

I need help with creating a request set. It's for the a custom report- requirement is to be able to schedule and run together the same report but for different values on just one parameter on the report. This parameter has 40 values, therefore report needs to be run 40 times with just that value being different each time.

I have created a request set containing the same report multiple times, just with that value on the one parameter differing. And it generated 40 output files. My question is this- is there any easier, more efficient way of doing it that I've missed? Thanks!!
