Define (setup) the default attributes for subtitles. When I have to add more than ten subtitles, and want them to have the same attributes, and I do not want to use the system defaults, going separately to each one and then setting the colors, fonts, positions and other attributes is troublesome.
This can be done in either of two ways. First, add this to setup. Second, put a check box in the interface, with a message, "Set the same attributes for all subtitles".
