Your request should probably be applied within a day or two.

I suppose what you're trying to achive can be applied using JavaScript, but javascript by itself can only be applied once your page has loaded, unless you make some sort of form in the editor and submitting it pastes an output in the page's textarea, and then publishing the page.
