Change default rich text placeholder info

[AJLaPorte_diagr]

The current placeholder text goes 

<h1>

<h4>

<p>

this isn't a normal structure and you wouldn't normally see a setup in this way with your headings. Is there a way to change this so you have an h1 > h2 > p setup instead? I know you can do so if you go into the module then choose options and customize it in there. Would be easier for templating if the default was simply setup as a normal sequence.
