How to combine two Webi reports?

Hi,

I have two Webi reports. What I would like to do is combine them into one report file so that I can have the file generate one report instead of two.

Is there a way to import another file so that it pulls in the data into one report?

Thanks,

Using shared objects might work, but they are for objects in reports not the entire report.

Using the Publication feature may work, but I think that generates separate files.
