Tinymce - adding custom formatting options


Is there a way of allowing the WYSIWYG, when using a HTML module, to allow us to define and/or remove options from the toolbar.

I’ve followed some of the other topics on here (unrelated, but still tried) and I couldn’t get the formats to load.

All we want to do is add another paragraph option, which preloads the class “intro”. Just so clients have and use the correct formatting object.
