If you have the paid version of RW, be sure to check out MS Word phrase feature. It allows you a way to easily make fully customized styles available in RW, giving you full control over your fonts. The styles only apply to the specific topic, but it is so easy to apply them to new topics with PE that this is a great stop-gap process until LWD allows you to create default and custom styles within the software. Here is how I do it:
First, create a new MS Word Phrase:

Unlike a plain text or formatted text phrase, when you try to edit it, it will open up Microsoft Word.

Customize the styles in MS Word and make sure that you have text in the document with a style applied to it for every style you want available in RW. You don't need a lot of text as the following example shows.

After you have your styles how you like them, close MS Word. Not need to save. You will not see the formatted MS Word text in Phrase Express. Make sure to give it an easy to type and remember trigger word. Here I used
#testformat

Then, when you are in a text snippet in RealmWorks, type your trigger word and a space and it will be replaced with the formatted text AND the MS Word styles are now available in RW for this topic.
