New caption design tool won't let adjust the design only for a certain part of a string
Right now, on the current caption tool, you could change the design of only one word or only some of the string on each caption.
Analyzing the new caption tool design option (currently available only on Beta), I found out it's impossible to do.
Please add this option before the official release.

Please do not place bugs or feature requests for beta software here. They will probably be ignored. Use the beta forums as that is what they are for. User Voice is for software that is already shipping and in official use. Thanks.
