Save PDF to Clipboard to paste into existing email reply or forward

I am a new Mac user and I figured out how to make a print workflow so that when I send a PDF to outlook it asks me for a file name so that when I email my clients the PDF filename is relevant - what I'm hoping someone can help me with is this:  Is there a way to create a workflow that:  1) asks me what to name the file 2) copies the resulting renamed PDF into my clipboard so that I can paste the file into an existing outlook message?  (I often print files to pdf and save them to desktop and then attach them to my reply)  I would like to save the steps in between.   All of my efforts so far have resulted in only the FILE NAME being saved into the clipboard rather than the PDF.
