asp.net merge instances of reportviewer to generate pdf

Hi,

I have a asp.net application that can run different crystal reports.

I've been asked to generate a single report containing these 3 different reports. Is it possible?

Also, is it possible to generate a pdf containing the main report as well as the subreports and not just asking the user to drill down on a pie chart and print each subreport one at a time?

Thanks

Elisabeth
