Can I save my CC settings in essential graphics? Seems like I can't. That would be nice to save a subtitle design.
The good news is that you can do both!
Once you have the subtitle lewk of your dreams locked in, choose the dropdown menu called Track Style and choose "Create Style." A new item will show up in your project panel, and you'll have a new option in the EGP under the Track Style menu. Change the Track Style dropdown to your new custom style, select all the captions in the timeline, and then use the little up arrow next to "push" the new style to all of the selected captions.
To use across projects, right-click on the Style in the Project Panel and select "Export Style." This will create a file that you can share across computers and import into new projects. As soon as its in the project, it will show up in that Track Styles dropdown in the EGP. Your imported styles will also show up in the Style dropdown in the EGP for text layers created with the main Text tool. (Not Legacy Titler).
I was able to select a word within a caption in the Program Monitor, and then italicize it without a hitch. Lemme know if that doesn't work for you though!
Cool to cross paths after so many years on this thing! lol.

Also seems that you can't italicize sections of text within one caption. So, for instance I wasn't able to italicize a movie title when mentioned by the speaker.
