Merging Reports

Hi,
I want to show 3 reports together in one report.

Suppose : Customer Id = 1009

I want to show below reports together

Report 1. Customer Ledger (Data should be shown in Detail Section of Report along with last line of Total)
Report 2. Post Dated Cheques (Data should be shown in Detail Section of Report right after Ledger Report)
Report 3. Dishonor Cheques(Data should be shown in Detail Section of Report right after Post Dated Cheques Report).

Please suggest the way

Regards
