Insert html word break opportunity

I've used <wbr> a lot in static html pages - it's handy for optional breaks in very long words (like URLs) in responsive pages where you don't want a soft hyphen.

Is there a way to insert <wbr> into text via the standard markitup interface? I find that if you simply type it into the text, e.g.,

tandläkarna/<wbr>sjuk­sköterskorna

it appears just like that, the same, in the browser page output.
