VBA - Is it Possible to Combine PDF's from within a macro?

I need to process an assembly. and create a combined PDF of the assembly drawing and all the details drawing...anyone ever done anything like this...

Can i combine PDF's from within SolidWorks VBA API?

I could even settle for create PDF of Assembly drawings, create PDF's of detail drawings, then combine all PDF's into a single PDF then delete the original individual PDF's

SolidworksApi macros
