Is there a way to wrap text editor content with html tags?

Question

I'm trying to implement syntax highlighter in SharePoint and have it working, but want to be able to use it in a list using a multi-text field. I would like to wrap the text that I paste into the editor with the <pre class> and </pre> tags with SyntaxHighlihter uses. Any ideas as to how to inject those tags into the RTE would be helpful!
