[plain][/plain] tags not working if no other crayon element on page

I sometimes like the use a
<pre></pre>
block for text that I want to highlight that isn’t actually code. I’m finding that I cannot do this unless I have another element on the post that contains a crayon. Is there anyway to manually add a post to the list that crayon syntax highlighter checks to see if it has a crayon on it so that the [plain][/plain] tag will work as a standard
<pre></pre>
tag? Or can you suggest another workaround to get the same results? I tried adding an empty
<pre></pre>
but that does not produce the desired results.

Thanks!
