Inserting RTF or HTML

I'm in my 60 day trial, and I would really like to be able to cut and paste HTML or, preferably, RTF into a Storyline textbox (like I can do in PowerPoint).

I mostly teach programming, and use Notepad++ to produce colour-coded text from numerous code-editors (e.g., Visual Studio).  NppExport is an add-in to Notepad++ that allows one to copy colour-coded text to the clipboard as either RTF or HTML, and I'm used to using this to paste that formatted text into my PowerPoint slides.  So, I'd like a way to do the same with Storyline.
