Dashboard Text Boxes Font Editor

The current dashboard 'Text box' style options are limited from few choices of Headings to normal text etc. It would be good if once you choose a style you can then modify it i.e. if I choose 'Heading 1' as the style then can change colour from the fixed Blue to say Red or make it Italic or bold or change even possibly the font type or size just like I can here in this window posting the Idea 🙂
