Ability to convert or make copy of a word document to PDF directly

At our firm, we know that a letter was sent out if there's a PDF version of the letter instead of a Word version. Word version is draft, and then we turn it to PDF to finalize. The ability to be able to creat a PDF copy right from CaseDocs would be useful. Or somehow have the ability that if we open the word document in Word (instead of just the embedded Needles word version because it has formatting issues) - when we click save or change to adobe PDF, the Save To file would directly open up into the OneDrive file for that case. . right now we have to manually go find the case folder in OneDrive to save it in there.
