How to merge two crystal reports into one in Delphi using TCrpe?

I am absolutely new to Delphi and Crystal Reports. I figured that I can export a crystal report to pdf like this:

      crpe.Clear;
    crpe.ReportName := 'BasicInfo.rpt';
    crpe.ParamFields[0].CurrentValue := '0';
    crpe.Output := toExport;
    crpe.ExportOptions.Destination := toApplication;
    crpe.ExportOptions.FileName:='C:\CoverSheet.pdf';
    crpe.ExportOptions.FileType:=AdobeAcrobatPDF;
    crpe.Export;
   

(Although this is working, please let me know if I am doing it wrong )

My main problem here is: I have two .rpts "BasicInfo.rpt" and "Details.rpt" and I need to create one pdf out of them in Delphi.

Is there any way to merge two .rpts and export it into one pdf in Delphi?
