The integrated process for applying detailed style controls is now available.
Once your script is complete, use the Style control panel on the right to edit the voices and characters to your liking.
Click [Apply to All] at the top of the Voice and/or Character panel in the project.
Please select the options you want to apply to all, including the range, by selecting either "Sentences by selected character" or "All characters", and then click [Apply].
You will then be able to see that the selected options have been applied accordingly.
