Autosave and combine pdfs

I am printing several reports to PDFCreator.  I have configured Autosave to automatically name the files and save to a directory.  There are eight reports that run which generates eight PDF files.  I would like to automatically combine these eight reports and then autosave as one PDF.  

I've attempted to research this and haven't found much information.  I know there is a combinejobs.vbs script in C:\\Program Files (x86)\\PDFCreator\\COM\\Windows Scripting Host\\VBScripts

I tried adding that script to the Action before saving and that didn't work.  Can someone provide some explanation or documentation of how to use the VBScripts in PDFCreator?  Is this even possible to combine PDFS and autosave?
