Is it possible to print Multi-page PDF files using the batch processor ?

I am using this VBA In MicroStation CONNECT Edition Update 12 to batch print Dgn files that contain a both model and a sheet and it works well but creates a separate PDF file for each Model/Sheet.  I would like it to create a single PDF file that contains all models/sheets for each DGN.  Does anyone know what in need to add to the VBA to make it create a single PDF file?

Sub PrintPDF_XXXX()
Dim DirPath As String
Dim FileName As String
Dim FileBaseName As String
Dim SaveFileName As String
Dim ModelName As String

CadInputQueue.SendCommand "MDL SILENTLOAD PLOTDLG"

CadInputQueue.SendCommand "PRINT DRIVER AE_SUB_pdf(no view).pltcfg"

DirPath = ActiveModelReference.DesignFile.Path
FileName = ActiveModelReference.DesignFile.Name
FileBaseName = Left(FileName, Len(FileName) - 4)
ModelName = ActiveModelReference.Name
SaveFileName = DirPath + "\" + FileBaseName + "-" + ModelName + ".pdf"

CadInputQueue.SendCommand "PRINT EXECUTE " & SaveFileName

CommandState.StartDefaultCommand
End Sub
