"Append to Existing pdf"
In MS Outlook you can create a pdf and add it to an existing pdf. (As in my attached screen shot)
Please make this available in Excel

Interestingly with NitroPro pdf when you print to pdf, choose to save as existing file name, it gives you the option to overwrite / append (to beginning) / append (to end).
Sorry to say that at this rate I might be returning to Nitro :-(
