Change font increment for WPF RichTextBox

I'm using a WPF RichTextBox control to input some text with user formatting capability, including font size adjustment. The built-in commands for IncreaseFontSize and DecreaseFontSize will adjust the font size by 0.75pt each time the command is executed. I would like to increase the granularity to 2pt.

Can this be done without implementing my own custom commands?

That doesn't work for InlineContainers that are text blocks

Unfortunately the value is hard-coded and you cannot change it. The fastest way to implement this is to use the TextRange class. Something like this:

var range = new TextRange( rtb.Document.ContentStart, rtb.Document.ContentEnd );
range.ApplyPropertyValue( TextElement.FontSizeProperty, 30.0 );
