How can we combine 3 reports into one report?

Hi People,

This is regarding EPM reports related question.

We already have 3 individual reports created and they are good. But now business needs these 3 reports into single report. Is there a possibility to combine these 3 reports into one single report?

Is there a way we can copy grids from one report to other report? or any best suggestion you can offer me?

Thanks
