Italics in process block title

Hello Mary! There currently isn't a way to modify the text format of the title/header of a Process Block. Would you be up for submitting a feature request to our developers here regarding the option you are looking for?

You can change the "Heading" under "Fonts" in your course themes to an italic font. However, this will apply to all the headers/titles in your course. Here's a screenshot for reference.
